[Dovecot] Problems with Dovecot 1.2.3 + IMAP (SSL) + iPhone OS 3.0

[Sascha Scandella]

Hello

Has anyone else problems with Dovecot 1.2.3? For clients such as 
Thunderbird, Outlook 2007 everything
works perfect. When I use an iPhone the child process is killed:
Aug 11 08:08:44 imap-login: Info: Login: user=<username>, 
method=PLAIN,rip=1.2.3.4, lip=4.3.2.1, TLS
Aug 11 08:08:44 dovecot: Error: child 5382 (imap) killed with signal 11 
(core dumps disabled)

Currently I have downgraded again to the working 1.2. I wonder if this 
problem is known or anyone
is looking for it.
