[Dovecot] 2.1.rc5 Cannot delete folders from trash

[Mike Constabel]

Hi,

If I delete a folder "foo" in Thunderbird, it is moved to trash.

[root at dovecot1][tmp:exec](~) # ll /mailspool1/xxxx.de/test1/mdbox/mailboxes/Trash/
insgesamt 16K
drwx------ 4 vmail vmail 4,0K 31. Jan 22:16 .

If I delete foo from trash, thunderbird removed it from view, 
but if I restart thunderbird, the folder is still in trash.

No error in dovecot log, no error in thunderbird.

with dovecot 1.2 and Maildir I can delete folders from trash.

Something wrong in my config? Thunderbird-Bug?
