Turned out to be a bit easier to fix (although very brute-force) by invalidating the entire cache.

A workaround is to clear your Horde cache. This is a nasty PHP bug. The data needs to be invalidated at the time the object is unserialized - since the object can be recreated at this time. It can't be checked/worked around at retrieval time. The only practical solution is to clear the cache as a login task in IMP. This can't be backed out of Horde_Imap_Client since the new data structure causing the issue fixes other bugs that are critical (e.g. broken e-mail parsing).

This appears to be a PHP bug. See: https://bugs.php.net/bug.php?id=61192

After installing the latest stable version of Horde_Imap_Client from pear (1.5.0) , the is a problem in IMP (traditional mode only, dynamic mode loads fine): [Wed Feb 22 23:32:36 2012] [error] [client 192.168.1.116] PHP Fatal error: __clone method called on non-object in /usr/share/php5/PEAR/Horde/Imap/Client/Data/Envelope.php on line 90, referer: http://webmail.example.com/horde/imp/ The summary of mailboxes loads without problems, but trying to display a message, the above error is logged and the frame is empty. This first started when I installed the latest stable version (1.5.0) from pear, reverting back to the previous version (1.4.4) restores this. At the time of this writing, the installation is up-to-date with pear (except for Horde_Imap_Client).
