Since last update of Kmail its not possible to move more than one email between
folders.

When I try to move one email from inbox to any folder, it is okay, the mail is
moved at once and disappears from original location. But when you select 2 or
more, it seemingly does not do anything and you still see all the mails at
original location. Closing and reopening KMail confirms that mails were
actually moved behind this graphical bug.

It makes sorting loads of mails pretty problematic as you need to constantly
close and open Kmail to see the effect of moves. As far as the sorting rules
are not helping much, this can be pretty annoying.
