Dear Maintainer,

   * What led up to the situation?
kontact crash often when I try to move a message from the inbox into another
folder

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
I tried to move a message from the inbox into a folder with the mouse move
action. First 1 clicked on the message and hold the button. I moved the mouse
pointer the destination folder. I selected in the popup window "move message".

I can reprdouce the error by deleting more than one message in one action.

   * What was the outcome of this action?
kontact crashed but not every time but often.

   * What outcome did you expect instead?
The message should moved to the destination folder or in the second case the
messages should deleted.
