Bug description:Crash related to custom session handler (via MySQL DB) in Roundcube
Description:
------------
I am getting a crash using Roundcube (http://roundcube.net/ at trunk
(r4231)), which is not easily reproducible.
It appears to be related (initially triggered) to forwarding some spam
related message and the internal session management in Roundcube (which is
using a custom handler, writing the data to a MySQL database).
Currently I can easily trigger the crash, but it might be difficult to
reproduce it somewhere else.
Here is a gdb backtrace, using PHP from Debian testing:

I hope this helps to track this down - I could do some more debugging, e.g.
add var_dump/breaking points into the Roundcube code, but it might be time
consuming to get a small test script.
