We are getting closer.  The problem is that _updateCache() should  
never be called unless we have UIDs.  We can't cache anything with  
sequence numbers, so if UIDs don't exist we shouldn't even reach this  
point.

So it would be great if I could get either a backtrace at the point  
where getUid() returns null (via Horde::debug() - see below) and/or  
the IMAP log of the activity that causes this issue (also see below).



Horde::debug() documentation: http://wiki.horde.org/Doc/Dev/DebugH4





To further debug this issue, we need details of the IMP -> IMAP/POP  
communication.

To enable debugging, see instructions contained in  
imp/config/backends.php (the 'debug' config parameter).

Debugging should not be enabled on a production server,   Attach/post  
only the portion of the log that directly deals with the problem  
reported (it may be simplest to clear the log file and then perform  
the event that causes the error).
