-- Information about the crash:
- What I was doing when the application crashed:
I use CTRL-` to reveal Yakuake (using OpenGL 3.1 w/Nvidia GeForce 750 GTX on
HDMI) and all input froze on the desktop. Could move mouse cursor, but the
desktop would not accept keyboard shortcuts nor mouse button events. Tried
Kwin --replace before this second crashed provided the dialog to report the
bug.
