Bug Description
Binary package hint: luciole
Information collected from luciole crash on a i386. to be linked with bug #481728
When using luciole under karmic the start of webcam acquisition crash the application.
The acquisition never start but the webcam is correctly detected. Tested with webcam philips SPC 1250. It runs ok with luciole under karmic. So it's a regression.
But, if cheese is started/stopped before using luciole. The webcam acquisition runs correctly on some architecture ( i386 on dell inspiron 640m)
Luciole operates correctly on imac alu 24" (amd64) under karmic ...
ProblemType: Bug

Impact of the bug: The webcam cannot be used to capture a movie, which makes luciole a lot less useful. The application freeze as soon as the user click on Capture button.
How the bug has been addressed in the development branch: by applying the same patch.
TEST CASE: after installing luciole, create a new project, by choosing webcam based. After finishing the assistant, you click on the 'luciole' button (acquisition one). Without this fix, it freeze.
#
Potential regression: as the webcam is not working right now, and the patch only affect the webcam output part, I don't see any.
