I haven't seen this in a while, either this has been fixed with some 
PHP changes or the code that triggered that behaviour is gone.

Not sure what we should do with this since I have never seen it, and 
if it is a PHP bug there may be little/nothing we can do about it 
except say "upgrade".

This seems to be a really weird bug in PHP, but only with PHP4 it 
breaks completely. Here's my backtrace:

Do you see that weird character where "int" should be in the parameter 
list to _setSorted()? Does anybody see this too?

This also happens on large mailboxes, like my trash folder. But not 
always, only the first time during the session. There also is the 
following warning first now:

Warning: Cannot convert to ordinal value in 
/home/jan/headhorde/imp/lib/Mailbox.php on line 616

Can't reproduce, with caching either on or off.

While viewing messages in a search result, I get the following fatal 
error when clicking "Back to search results":



Fatal error: Call to undefined function: findbody() in 
/home/jan/headhorde/imp/lib/IMAP/MailboxCache.php on line 528



Mailbox cache is off.
