Dear Maintainer,

FWIW, I just installed jessie and dist-upgraded to testing and I see this in my dmesg:

and many, many, many more.
So, not sure what's going on, but it's continuously segfaulting here.

I think it started when I plugged in my USB camera. But I'm not sure, as unplugging it doesn't stop it...
