Version: Dovecot v1.1.rc3 OS: CentOS 5 running in OpenVZ CPU: x86_64
Was running fine with maildir and decided to get dbox a try. Test user created with a dbox mailstore backend and when a client logs in that tries to run a getquotaroot imap command the process SIGSEGV's.
Have been able to narrow it down to dbox crashing against dict quota as well as dirsize. Maildir works just fine.
example telnet session:
... 5 getquota *
5 NO Quota root doesn't exist.
6 getquotaroot inbox
Connection closed by foreign host.
Got the backtrace from a coredump as well:
Program terminated with signal 11, Segmentation fault.
