Bug#810947: kwin-x11: iceweasel locks up when multiple windows restored
Package: kwin-x11
Version: 4:5.4.3-1.1
Followup-For: Bug #810947
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
The problem still comes and goes semi-randomly when updating various packages.
This time when it locked up I ran gdb on the hung kwin_x11 process and have
attached the log including backtrace.
* What exactly did you do (or not do) that was effective (or
ineffective)?
* What was the outcome of this action?
* What outcome did you expect instead?
