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?
With current kernel and libraries, first time to attempt restoring
iceweasel can still lock up when restoring multiple windows, but after doing
a kill -9 on the locked up kwin_x11 process, allowing iceweasel to restore
windows and shutting things down cleanly, logging out and doing an init 1
to even restart dbus, the next login and iceweasel session restore works
without any lock-up.
* What exactly did you do (or not do) that was effective (or
ineffective)?
I attempted upgrading kwin-x11 to 4:5.5.4-2 but that would lock up right
at the start before attempting to run any programs like iceweasel or konsole.
(See attached back-trace).
* What was the outcome of this action?
* What outcome did you expect instead?
