> Failed to do pygdbmi parsing: No module named 'pygdbmi'
> frame={level="0",func="onWindowResize",file="/home/aronkvh/.local/share/kwin/scripts/kdesnapassist/contents/ui/code/windows.js",fullname="/home/aronkvh/.local/share/kwin/scripts/kdesnapassist/c".
This is an issue caused by a bug in the 3rd-party Snap Assist KWin script. Evidently your system is missing the "pygdbmi" python modue, and this causes it to crash. You should be able to fix this by installing that module, and you should also report tihs to the developer because the script shouldn't cause KWin to crash if it's missing that module.

Thanks for the explanation, reported it. (In reply to Nate Graham from comment #1) > This is an issue caused by a bug in the 3rd-party Snap Assist KWin script. > Evidently your system is missing the "pygdbmi" python modue, and this causes > it to crash But this script doesn't depend on "pygdbmi" module, or any other external libraries or modules other than the official KWin Scripting API. The fact that the crash happens only after waking from sleep also makes me suspicious. Is it possible that "clientArea()" method from the API somehow requires "pygdbmi" dependency under the hood? As it seems to be the exact place where the crash happens. pydgbmi (https://github.com/cs01/pygdbmi) is related to GDB, i.e. what happens after the crash. It has nothing to do with the snap assistant or the actual cause of the crash This looks a lot like https://bugs.kde.org/show_bug.cgi?id=448102 pygdbmi is used by DrKonqi when creating crash reports With current master
