Cannot delete folder

I couldn't find anything relevant between all the debug log lines. Is 
that in /var/log/mail.log?

Here's the lines I think are related to creating and deleting the folder:

> May 21 10:36:14 mond2 dovecot: imap(yg@****.de): Debug: Namespace : /var/mail/virtual/****.de/yg/.Test doesn't exist yet, using default permissions
> May 21 10:36:14 mond2 dovecot: imap(yg@****.de): Debug: Namespace : Using permissions from /var/mail/virtual/****.de/yg: mode=0700 gid=default
> May 21 10:36:23 mond2 dovecot: imap(yg@****.de): Debug: Namespace : /var/mail/virtual/****.de/yg/.Trash.Test doesn't exist yet, using default permissions

That's it.

Thunderbird shows an error message with: [CANNOT] Renaming not supported 
across conflicting directory permissions (0.000 + 0.000 secs).

Assuming '8' = mail, i cannot see anything wrong here...

Can you turn on 'mail_debug=yes' and attempt folder deletion, and check 
logs after that?
