Indeed, it's a long time known issue with in nouveau. From time to time, 
there is error that pops and could not get handled. It often, but now 
always lead to system freeze. Why is GStreamer often implicated, simply 
because of the large flow of data being sent to Nouveau during video 
plaback. I've seen hard freeze without GStreamer too, and on recent 
kernel, older Nvidia chipset, this freeze is triggered also by 
suspend/unsuspend. Nouveau need help, but not an easy task as it's 
reversed engineered. Please don't be too rude on the few devs doing this 
hard work, simply report and provide all the information you can.
