Thu, 09 Apr 2026 21:37:09 +0000 https://bugs.horde.org/ticket/6380 IMP / DIMP display problems with some HTML email We've got some locally generated HTML email that isn't viewable in IMP 4.2RC2 / HEAD, or DIMP 1.0RC2 / HEAD (but is viewable in our currently deployed IMP 4.0.5). Selecting the message brings up a blank message page (with all the headers and stuff, but no content). We do see "Show this HTML in a new window?", and selecting that opens a new window with nothing in it. "View source" in the message page, or the "new window" doesn't reveal the message text. "Message Source" does reveal the text of the message, however. No errors in the error log, nothing interesting in the horde log, and no core dumps. PHP 5.2.5, IMAP 2007. I've tried it both with the Tidy extension loaded and without. The messages in question are multipart messages - HTML, with plain text alternatives. The HTML portions have CSS embedded in them, rather than calling on external style sheets. Wed, 05 Mar 2008 23:02:39 +0000 https://bugs.horde.org/ticket/6380#t43416 The message renders fine for me in CVS HEAD. I bet that c-client can't parse the message for some reason. Wed, 05 Mar 2008 23:54:53 +0000 https://bugs.horde.org/ticket/6380#t43419 Can you suggest a known good c-client version? Thu, 06 Mar 2008 00:05:38 +0000 https://bugs.horde.org/ticket/6380#t43420 I am running version 2004 since ages and never had problems with any message that users provided as being problematic. I am already considering my install as a reference system. ;-) But honestly, I would start with the most recent version first. Thu, 06 Mar 2008 00:22:34 +0000 https://bugs.horde.org/ticket/6380#t43428 The most recent release is 2007. 2007a-DEV is also available. I've got a number of versions in my build tree, I'll rebuild it against something earlier. Thu, 06 Mar 2008 00:51:38 +0000 https://bugs.horde.org/ticket/6380#t43450 I tried rebuilding it against IMAP 2006j, 2006h, and 2004g. Didn't fix it. I tried reverting to PHP 5.2.3, w/imap built against 2006-h, which did work.. so, I reinstalled 5.2.5, but kept the imap module from 5.2.3, which surprisingly, didn't work. Any other ideas? Thu, 06 Mar 2008 01:37:11 +0000 https://bugs.horde.org/ticket/6380#t43451 I tried the imap extension from my PHP 5.2.5 build with 5.2.3, and the messages display properly. What other change between 5.2.3 and 5.2.5 could alter this behavior? Thu, 06 Mar 2008 01:52:13 +0000 https://bugs.horde.org/ticket/6380#t43453 As mentioned on the list, try disabling tidy if it is installed. Thu, 06 Mar 2008 02:41:46 +0000 https://bugs.horde.org/ticket/6380#t43455 I tried removing tidy. When it works, it works regardless of tidy being installed / enabled. Thu, 06 Mar 2008 03:08:04 +0000 https://bugs.horde.org/ticket/6380#t43456 This messages renders fine for me using PHP 5.2.5 and imap-2006i. Since none of the devs can duplicate, you will need to debug on your own.

We tracked the problem down, and according to CVS so did you! :) http://marc.info/?l=horde-cvs&m=120607658204239&w=2 For the record, we were hitting PHP's pcre.backtrack_limit, new to PHP 5.2, which fails silently. Bad PHP. Thu, 10 Apr 2008 15:38:33 +0000 https://bugs.horde.org/ticket/6380#t44572
