Segmentation fault on webcam detection when acqusisition is on

[NicoInattendu]

Binary package hint: luciole

On luciole version 0.8.2 on lucid

If webcam detection is started, on project properties window and webcam acquisition still active, luciole goes on segmentation fault. Only on lucid, no segmentation fault on karmic

For robustness better to stop acquisition, before launching project properties windows.
