Confirmed in KMail 1.9.9 (KDE 3.5.9) and trunk.

The problem is that the "New Subfolder" button is disabled in KMFolderSelDlg::slotUpdateBtnStatus() by:

  enableButton( User1, folder() &&
                ( !folder()->noContent() && !folder()->noChildren() ) );

For the root of the folder tree, folder() is NULL and so the button is disabled.

There isn't a simple fix of just enabling the button and accepting NULL as meaning "root", because the required parent folder is passed down to KMFolderTree::addChildFolder().  There, a folder of NULL means "current selected item", which would create the new folder under the selected folder in the *main folder tree* (not the tree displayed in the dialogue).

May need to add an additional parameter to addChildFolder() to specify "ignore what is selected in the GUI".
