I tried that. In addition to that I did Trash -> Context-Menu -> 
Settings and "Repair". I also deleted Trash.sdb and Trash.msf in 
ImapMail-Dir of given Mailbox (after closing Thunderbird of course and 
restart afterwards). I think the repair-button does more or less the 
same than deleting msf-files.

Trash was rebuilding... but the Folders are still there. I was able to 
get rid of some other "Junk folders" (that not even where shown in my 
Thunderbird-Trash inside Trash.sdb folder). But the folders causing 
current issue are still present after sync! And on server-side (vmail 
Mailbox on imap-server) these folders are also there!

I'm still not able to delete them in Thunderbird. Still getting error 
Folder contains children, delete them first". Obviously this isn't 
possible as those sub-folders are not shown in Thunderbird! On 
server-side of imap (vmail Mailbox) there are in fact sub-folders in 
those folders.
