over the holidays I tried Jitsi on my fathers windows 7 laptop. On this laptop
the video camera can be en-/disabled by pressing FN+F6.
First the camera was disabled. When I tried to switch to the video tab in the
options, I saw the camera selected in the dropdown and a second later Jitsi
crashed with a dialog box asking me whether I want to restart Jitsi.
After enabling the camera with FN+F6, everything worked fine.
I didn't have time to collect any backtrace and I don't have access to the
laptop anymore, so that's all I can give you.
I started jitsi from the windows command line. It did print something
unrelated right after starting, but nothing when it crashed.
