This is two bugs: the crash and the recording problem. Please file a new bug for the crash. Also, please do not attach stack traces to bugs in GNOME Bugzilla, instead simply paste the stack trace into the comment field (this way it will be analysed by the stack trace extension). Also, for the original bug, please use the latest stable version of Cheese (3.6.0 currently), as it has switched to GStreamer 1.0 and therefore has had many changes to the video encoding pipeline.
This are not two bugs. The recording problem causes the crasher. When you follwing a bit on launchpad you see that the first occurences was with cheese 3.5 , but is veryfied by others to occure on 3.6.0. Following the reproducing procedure occures now in the crasher.

(In reply to comment #6) > This are not two bugs. > > The recording problem causes the crasher. Frankly, that is not certain, so please either do as I ask or further triage the crash downstream. > When you follwing a bit on launchpad you see that the first occurences was with > cheese 3.5 , but is veryfied by others to occure on 3.6.0. I see that for the second bug, which the stack trace was generated from, Cheese 3.6.0 was used, and for the first bug, which this bug was reported from originally, 3.5.5 was used. The 3.5.5 bug should not have been filed upstream without attempting to verify the problem with the latest version of Cheese. > Following the reproducing procedure occures now in the crasher. The steps to reproduce the bugs are different: for the first bug the video is frozen and stopping the recording does not produce a video file and for the second bug the crash occurs when trying to record video. Please triage the bugs fully before filing them upstream or I have to spend too much time trying to figure out what the problem actually is. In short, the crasher bug seems to be the only bug that can be verified of the two, so please file that as a new bug. Closing this bug as INVALID.
