My IMAP account has got folders with only sub-folders in them, and no messages. When kmail2 scans the server, it reports an error every time:

"Select failed, sever replied: A002692 NO Mailbox isn't selectable: XXXXX [ CANNOT ]" where XXXXX is one of the folder names.

Adding a message to the folder doesn't help.  This only started happening on the  very latest Kubuntu packages.

Reproducible: Always

Steps to Reproduce:
Create a folder that contains "only folders" on an IMAP server

Actual Results:  
"Select failed, sever replied: A002692 NO Mailbox isn't selectable: XXXXX [ CANNOT ]" where XXXXX is one of the folder names.

Expected Results:  
No error popups.
