Hangs while recording with audio input not set to 'Webcam microphone'

[Mahendra Tallur]

Binary package hint: cheese

Here's an issue I can reproduce every time, using Ubuntu Maverick AMD64, with no ppa and no "proposed" update.
Logitech C300 USB webcam (uvc)

1) launch Cheese
2) the webcam is detected / initialized properly : one can see the video preview and take pictures etc with no problem at all
3) when starting an actual recording : the picture is frozen but the GUI still seems to answer
4) when stopping the recording : cheese is completely frozen : I have to kill it
5) when restarting it, Cheese works as before (preview etc.) I can see one video file was added to the list below the picture but the file is empty.

What occurs : no preview WHILE recording, GUI hangs when stopping recording, video file empty
What should occur : preview while recording, proper video file, etc.

Cheers !

BTW : I would like to obtain a backtrace, when there is apparently no "cheese-dbg" package in the repositories.
If necessary, I will also report the bug upstream.

Here is an important additional piece of information :

it turned out that :

- when choosing in the PulseAudio mixer the Logitech Webcam as audio input source (instead of the internal line-in), Cheese doesn't hang anymore
- HOWEVER : the first video is recorded properly but if I record 2 videos in a row, the GUI doesn't hang but the subsequent video fils are empty. I have to quit / relaunch Cheese.

So it seems there are 2 distinct bugs here :
https://bugzilla.gnome.org/show_bug.cgi?id=626689
and
https://bugzilla.gnome.org/show_bug.cgi?id=630499

I think this bugreport should only focus the 1st issue. Can someone change the bug description ? It should rather be :

"Cheese hangs when recording a video when the audio input is not set to the Webcam microphone"

The relevant Gnome tracker bug being : https://bugzilla.gnome.org/show_bug.cgi?id=626689

I have the same problem with a Logitech Quickcam E3500 which worked of previous versions of Xubuntu and currently works on this version Maverick 64 if I use Kamoso. as soon as I try to record video the program freezes with a frozen image and a video file is produces of 0kb.
