Version:           4.8 (using KDE 4.8.0) 
OS:                Linux

I have a mailbox, where some user folders are added as subfolders of "user":
+-...
+-Inbox
+-user
| +-Finance
| +-...
...

The folder "user" is marked with flag \Noselect, but the subfolders ("user/Finance", ...) are not. They are being correctly selected, but the SELECT on folder "user" is also performed with result "No such mailbox.".
A part of traffic dump follows:

        Request Tag: A000005
