Not sure what happened there, thought I had applied it.

So yes, now if via_v4l_drv isn't loaded I get a nice friendly error 
telling me to check my installation. Thanks.


But if I modprobe via_v4l_drv in and repeat I get a segfault in the 
frontend or it just hangs in the debugger.
  :-(

Thanks

Carey
