[Bug 18563] Re: selection of all messages is reapplied when filter changed

[Bauduin Raphael]

Filter the message to only show important messages -> only important messagedes are displayed.

Then, press CTRL+A to select all displayed messages (even if no message
is displayed)

Changes status filter to show all messages. At that time all existing messages
are selected, but only important messages should be selected. 

Not sure this is still the case, kontact/kmail refuses to start on my PC
now :(
