All Dovecot crashes are bugs. The problem with this panic is that I just can't reproduce it, so I don't really have much ideas what exactly causes it.. You mentioned just connecting with K9 can cause it, but that's not what Juergen's backtrace showed. Maybe the step you could do is to get gdb backtrace? http://dovecot.org/bugreport.html And hopefully manage to reproduce it somehow easily? Also rawlog from such crashing session could be helpful too (see my previous mail).
