[Dovecot] 1.1.beta8 crashes with segfault when SIGHUP

[arvids]

Hello,

dovecot crashes when it receives -HUP signal. It happens always if there was 
some activity - for example, if I start dovecot, check any account through 
POP3 and then send -HUP to dovecot process, it crashes with the following log 
entry:
	segfault at 00000008 eip 0804d3fb esp bfdd3860 error 4
If there were no activity at all since starting, it does not crash.

my dovecot -n output:
