Or you could just "touch userdb".

Could you do:

gdb dovecot
x 0x17d2c

Hmm. I guess this could be fixed by simply returning from the function
if it returns EAGAIN..

Could you get gdb backtrace from this? Since it's dovecot master
process, it should write core to /var/run/dovecot/ (assuming you had
ulimit -c high enough).

I don't think I've broken anything related to this since beta7, but it
might work a bit differently so that you just don't see this problem
with it..
