[Dovecot] segfault in Debian Squeeze + Dovecot 2.1.10

[Joe Auty]

Hello,

I'm seeing a lot of these in my /var/log/messages in Debian Squeeze, I 
suspect this might be causing performance issues. Any suggestions what I 
can try to fix this?

> sp 00007fff49d385c0 error 4 in libdovecot.so.0.0.0[7f9ff837c000+8b000]

I'm using the 2.1.10 packages obtained with the following in my 
sources.list:

deb http://xi.rename-it.nl/debian/ stable-auto/dovecot-2.1 main


I need to use Dovecot 2.1.x because I need to support handling multiple 
SSL certs.
