KWin crashes after sleep with snap-assist enabled

[thegrasshopper104]

Hi, > 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". Kwin broke or restarted every time after installing the script and waking from sleep. It was fixed by installing pygdbmi. Bug against KWin. System info:

Hi! Thanks for reporting, I think I can add this under the "Troubleshooting" section. But I'm not sure if I should make the script to install this library automatically, as the script doesn't use it, as well as any other external modules or libraries.

The crash has nothing to do with pygdbmi

What seems to happen is that in https://github.com/emvaized/kde-snap-assist/blob/main/contents/ui/code/windows.js#L89 a null window is passed

#5  KWin::Window::output() const (this=this@entry=0x0) at /home/nico/kde/src/kwin/src/window.cpp:421

@nicolasfella Thanks a lot for your investigation! Then it must be an easy fix of simply adding a null check.

I just published a new 1.6.1 update which will hopefully resolve this issue. Please feel free to reopen if the issue persists.
