dovecot - Jul 2010 - dovecot 2.0rc2 [SERVERBUG] When trying to remove a folder which contains a subfolder

I'm going to risk to report something stupid again and waste
resources... but [SERVERBUG] sounds like it should not happen. :)

g create test
g OK Create completed.
h create test/test2
h OK Create completed.
i list "test" "*"
* LIST (\HasChildren) "/" "test"
* LIST (\HasNoChildren) "/" "test/test2"
i OK List completed.
j delete "test"
j NO [SERVERBUG] Internal error occurred. Refer to server log for more
information. [2010-07-17 22:57:48]

The log has the following entry:
Jul 17 22:57:48 azati dovecot: [ID 583609 mail.error] imap(ski):
Error: rmdir(/l/dovecot/ski/dbox/mailboxes/test) failed: File exists

Which is correct
$ ls /l/dovecot/ski/dbox/mailboxes/test/
test2

Deleting the mailboxes in sync does work.

k delete "test/test2"
k OK Delete completed.
l delete "test"
l OK Delete completed.
m list "test" "*"
m OK List completed.

Probably fixed by: http://hg.dovecot.org/dovecot-2.0/rev/6ebe8d8fd1fd
