[Dovecot] 2.2rc2 core dump
Hi,
using dovecot 2.2rc2 I got core dumps during IMAP subscription change if the CONTROL directory (specified in mail_location) does not exists.
userdb_mail: mbox:~/Test:INBOX=~/Test/heiko:INDEX=~/.imap/index:CONTROL=~/.imap/control
If ~/.imap/control does not exists, dovecot crashes. See below for log msg, full backtrace and configuration.

I can't reproduce this with latest hg, so I think it's fixed?

Latest hg is not so easy as you commit every few minutes.
Testing with one hour old changeset 16065 ab434891f2af failed during compilation:

So I reverted changeset 16040 70dd78cd89ab and run into the next problem:

Maybe I should wait until tomorrow and check when your are finished with your currect coding activities.

The Makefile is out of date. You need to run autogen.sh and configure again. Or use configure --enable-maintainer-mode so you don't have to remember to do that.

Yes, sorry.
But it still crashes if I subscribe and the CONTROL=... directory does not exists:

After creating the CONTROL=... directory manually with mkdir it works without problems.

Not sure why I couldn't reproduce it earlier, but I could now. These fix it:

Thanks. I can confirm that it is fixed in v2.2.rc3.
