[Dovecot] Segfault in ACL Plugin + user shared folders
Hi Timo,
I have another problem, this time with user shared folders:
User "markus" shared the folder "ForTest" to test:
SETACL "INBOX/ForTest" test akxeilrwts
dovecot-acl and shared-mailboxes.db have been successfully updated.
As user "test" the folder (and "#User" namespace) is not
visible.
When I configure the shared namespace with "list = yes", the namespace
and folder became visible and accessible, but lines like this are logged:
Apr 7 22:08:58 asterix dovecot: IMAP(test): acl vfile: reading file

When I try to access the folder directly with "list = children" set,
then
dovecot segfaults. Last lines in logfile:

The backtrace looks like the one I got with your first quota fix, but
quota works now and this error is reproducible with or without the quota

With "list = all" now there is a folder named "%" listed, directly under "#User/", additionaly to "markus at example.com". Accessing the folder "markus at example.com/ForTest" with Thunderbird results in a segfault. Mutt works.
