Package: gnomemeeting
Version: 1.2.1-1
Severity: normal

 I setup gnomemeeting with the default settings for my webcam. I have a
 Phillips Quickcam 3000 Pro and I built the pwc driver using the
 qc-usb-source package. v4l2 was selected by default, and I was able to
 successfully run all tests for audio & video. At first I was able to
 see a horizontal and vertical red &green lines. When i restarted
 gnomemeeting I immediately began getting the segmentation faults.
 The exact error is : lib: unexpected async reply (sequence 0x724)!
 		      Segmentation fault
 This error apparently was caused by the use of v4l2 which have been
 told is an experimental and unstable package. What I don't understand is
 why this was chosen by default. After uninstalling libpt-plugins-v4l2
 the segmentation faults stopped and I was able to successfully
 setup gnomemeeting with v4l. The video is perfect just as it was in
 camstream. Shouldn't the user at least be warned that v4l2 is unstable,
 and why isn't v4l used as the default? Doesn't it work with most
