[Dovecot] Segfault in dovecot 1.2rc2 with quota + public namespace enabled
Hi,
I have configured a public namespace ("#Shared"). Since dovecot 1.2rc2
(1.1.11 worked fine) I get a segfault, if I try to access a folder
under this namespace when quota plugin is enabled. When the quota
plugin is disabled, accessing those folders works.
$ dovecot -n
