Description Štefan Gurský 2018-11-07 21:15:53 UTC 
Description of problem:
I was using gnome Cheese with (built in, but reported as USB connected) laptop camera.
And while using it, I decided to block the camera in usbguard. Then I got this crash.
So, it is kind of self-inflicted crash, but what would happen with usb camera which got disconnected while in use?
