Crash after configuration on Linux

[kekonn]

I get a crash after clicking "Save and continue". I also tried setting QT_QPA_PLATFORM to xcb but that only removes the line complaining about Wayland. I still get the sigsev.

This error was using the 0.7 beta.

Upon some further investigation it looks like this might occur when the video device isn't available. Perhaps a good idea to not outright crash but display an error message in that case.
