[UPDATE]: Another Crash in service imap with version 2.2.13 - Debian Wheezy
Hi,
short update.
I switched back to Debian Squeeze. Same Dovecot Version 2.2.13.
The crash happens also on Squeeze.
Very strange is that the crash don't happened yesterday.
And it happens only to one certain user. Other users with the same iOS
"os-version=7.1.1 (11D201)" aren't affected.
Also very strange is, that the crash doens't happen every time (I don't
saw that before).
Logs in cronological order from the last attempt:

The last session has been endet normallly. Very strange to me.
I think this is a problem only with that specific user and his Iphone.
On the other hand, the crash isn't fine at all.
Thanks
