I'm using Gnome 3 on 12.04 and trying to create a screencast. I start the screencast using the Ctrl-Alt-Shift-R shortcut and the red light appears in the bottom right corner. I go about my business then press the key combination again when done. The problem is that the screencast file gets generated maybe 1 out of 10 times.

Is there a log file I can look at to determine the issue? How about a settings file?

UPDATE:

I did some additional testing. What's happening is that the screencast does work but it appends the new video to the existing file. Even if the file is renamed or moved to trash. Emptying trash does not create a new file either. Not sure where the video gets recorded to then.

The only reliable way I've found to have a new file created is to log out of the session and log back in.

Is this expected behaviour? Is there a way to force screencast to create a new file every time Ctrl-Alt-Shift-R is pressed?
