Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
   * What exactly did you do (or not do) that was effective (or
     ineffective)?

After experiences problems as late as yesterday 23 January and applying some
upgrades today, both my usual session and a test account were able to launch
iceweasel with multiple windows (16) being restored without any lock-up of
kwin_x11.

I'll keep checking to see if they problem stays away.

   * What was the outcome of this action?
