Hi, History of this bug seems broken. See http://bugs.horde.org/ticket/7181 page, where I've only one entry in the history log containing : Fatal error: Uncaught exception 'Horde_Mime_Exception' with message 'Validation failed for: ryan @ localhost' in /var/www/dev.horde.org/horde-git/framework/Mime/lib/Horde/Mime/Address.php:390 Stack trace: #0 /var/www/dev.horde.org/horde/whups/lib/Whups.php(564): Horde_Mime_Address::parseAddressList('ryan @ localhos...') #1 /var/www/dev.horde.org/horde/whups/lib/Whups.php(617): Whups->getUserAttributes('-53112_transact...') #2 /var/www/dev.horde.org/horde/whups/lib/Renderer/Comment.php(180): Whups->formatUser('-53112_transact...', false, true, true) #3 /var/www/dev.horde.org/horde/whups/ticket/index.php(48): Horde_Form_Renderer_Comment->render(53112, Object(Variables)) #4 {main} thrown in /var/www/dev.horde.org/horde-git/framework/Mime/lib/Horde/Mime/Address.php on line 390 Regards

Is there anything else I can do to help debug? Other than tracking down the exact cause of the error (useful advice, I know), no. As mentioned, this code has already been removed (well, rewritten at least and moved to the Imap client library) in IMP 5/Horde 4 so the underlying issue has already been addressed in the dev code.

That change definitely fixed it. imp no longer crashes. I have yet to confirm whether this will make the caching system work, but there are no error messages and the message list is coming up. Is there anything else I can do to help debug?

Doesn't help me out much - still don't know why the data is null (stored data value) vs. false (indicating that the cache value doesn't exist). Not worth tracking down since all of this caching code has been removed in IMP 5. Try the fix contained in the last comment and let me know how that works.

I have no idea if any of the below is useful, but I repeated the output using var_dump($ptr) as Michael had suggested later in a follow-up post. I got 16MB of text output that I pruned extensively. I've looked through my apache_log and error_log and can't find any errors. There are no errors reported to syslog as far as I can tell either. This occurs when trying to enable memcache with caching the message list in imp. object(PEAR_Error)#23 (8) { ["error_message_prefix"]=> string(0) "" ["mode"]=> int(1) ["level"]=> int(1024) ["code"]=> NULL ["message"]=> string(23) "Unserialization failed."

I am having this same problem with horde 3.3. It crashes with the same error whenever I enable memory caching. I want to help with the debug, but I don't understand the instructions that Michael wrote on 08/20/2008. In my Cache.php file, there is no Horde_Serialize::unserialize() line. There is also no $res variable as far as I can tell. In the getCache function, if I put in the print_r($ptr) line just after the $ptr variable is declared on line 78, then I get the same output that the original poster made. I'd be happy to provide more information or run a debug somewhere else, but I need more detailed instructions.

As long as nobody provides the information requested by Michael, the developer won't take any further look into this.

That print_r() has to return something or else there is no possible way the code could reach that point (the code would short-circuit that section if the variable was truly empty). You can try replacing print_r() with var_dump() and see if that helps. And if PHP is crashing, an error message has to be output somewhere (unless you have somehow configured your webserver to redirect all standard output/error from PHP to /dev/null, which is a Bad Idea).

Hi, I am also hitting this bug when enabling cache driver "eaccelerator" in horde/conf.php According to your e-mail on the mailing list, this is not the same issue. Your eaccelerator is broken. This ticket describes an error dealing with the content of the cached data. That's correct. Based on the posting you referred me, I recompiled the eaccelerator-0.9.5.3 with the settings below. That alleviated one problem with eaccelerator_get() function and brought me this bug that we are discussing here. './configure' \ '--with-eaccelerator-shared-memory' \ '--with-php-config=/usr/local/bin/php-config' \ '--with-eaccelerator-content-caching' \

Including the print statement suggested didn't help: Of course it doesn't. It is not supposed to fix the problem, but to output information that helps us localizing it. So, what output does it generate? Sorry, you're right. I basically get a blank screen on the main page and no additional messages or errors other then the one regarding PEAR object.

What do you do to get this to happen? What are the actual versions involved? According to the PEAR_Error output, looks like the cached value is empty. We could change the: $res === false check to: empty($res) since if the return is empty, we know there is no serialized data anyway. But it also would be good to know why we are setting the cache value to empty (assuming it is the code that is causing this and not a bad installation, etc.)
