Bug#834359: kwin-x11: Kwin crashes when launching thunderbird or firefox almost each time.

[valette <eric.valette@free.fr>]

Package: kwin-x11
Version: 4:5.7.0-1
Severity: important

I keep having visual glitches when launching either firefox or thunderbird
because kwin crashes almost sytematically (at least 8/10).

I have the error message for kwin in the message box but no backtrace
no nothing. Once automagically restarted it works correctly.
