Application: kamoso (19.12.3) Qt Version: 5.14.1 Frameworks Version: 5.68.0 Operating System: Linux 5.5.13-arch1-1 x86_64 Windowing system: X11 Distribution: Arch Linux -- Information about the crash: - What I was doing when the application crashed: Opening Kamoso with webcam plugged in. When it's unplugged, this doesn't happen. Kamoso opens fine. When the webcam gets plugged in Kamoso will then crash. I plugged the webcam into a different USB bus and received the same result. - Custom settings of the application: $ sudo lsusb -v -s 001:007 Bus 001 Device 007: ID 046d:08aa Logitech, Inc.
