Yes, I have tried with "plain" value and it works fine. But is it normal that not valid value cause segmentation fault at all?

Did you try with
a) http://hg.dovecot.org/dovecot-2.2/rev/afd3cfcf1bcb patch which should fix the crash
and/or
b) Changing auth_verbose_passwords=plain (because "yes" isn't a valid value)

Sorry, it was my fault. With "plain" value all works fine.

Either use "plain" or "sha1". Although I suppose "yes" could be an alias for "plain" to make people's life easier.
