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.
