[Dovecot] Imap segfault on login with version 2.0.8 & 2.0.11

Hi everyone,

I'm trying to upgrade/test our configuration files from Dovecot 1.2 to 2.0.11.  I used the Dovecot config convert command, created a RHEL 5 x86_64 rpm, and tested it.  I can connect, but once I login, the IMAP service segfaults.  I've also reproduced this on version 2.0.8.

I installed the debug RPM (for the stripped symbols), took a look at the core dump in gdb, and just got the _start method in ld_preload and a broken pointer in the backtrace.  I tried to strace everything but the segfault doesn't happen then :-).  I'm not sure what to do to get better information.

I attached my client session, dovecot -n output, gdb trace, maillog, and the core dump.

I published the RPMs I made at:
http://c3205012.r12.cf0.rackcdn.com/dovecot-2.0.11-1_125.x86_64.rpm
http://c3205012.r12.cf0.rackcdn.com/dovecot-debuginfo-2.0.11-1_125.x86_64.rpm

My platform is RHEL 5 with kernel 2.6.18 on x86_64.

Is there anything else I can provide for more info?

Thanks,
Nick
