Cannot delete IMAP Mail-Folder in Trash

[Rupert Gallagher]

We have the same problem, with a twist. When Thunderbird deletes a folder, it is still shown by the GUI. Dovecot deleted the folder correctly, and the sunscriptions file is also correct. Some other times, on shared folders, Thunderbird refuses to delete; in this case, apple mail on iphone can delete successfully. This suggests that the problem is in Thunderbird's code.
