Hello Timo,

latest 2.0 hg version (changeset a6b050cc4a9a) segfaults when selecting a virtual mailbox.

The attached patch fixes this for me.

Hello Timo,

This crash still happens in beta6. Actually it crashes on 'getquotaroot <virtualmailbox>'. The patch posted earlier still works but there is probably a more elegant way to fix it ...

Hello Timo,

Oh, there was a patch. :) I was just lazily delaying reading all virtual plugin related mails.. Applied the patch, slightly differently: http://hg.dovecot.org/dovecot-2.0/rev/7d05cef711bb

Thanks Timo! It works :)
