[Dovecot] coredump while accessing virtual folder with dovecot 2.0

19 Jun 2010


      Hi,
I get a core dump with 2.0.beta6 (573cb66e9180) when I access virtual
folders with the master user. Since ACLs are active I have to set a global
ACL in .DEFAULTS to access all folders.
Coredump:
Core was generated by `dovecot/imap'.
Program terminated with signal 11, Segmentation fault.
