Non-stop screencaps when S is hit

What steps will reproduce the problem?
1. Load a video
2. Press <S> to screenshot (the usage of capital S means that Caps Lock is 
activated)
3. Find a way to kill gnome-mplayer process. 

What is the expected output? What do you see instead?
I expect a single screenshot to be taken and stored in my ~/ directory. 
Instead, gnome-mplayer takes nonstop screencaps and the only way to stop is is 
by killing the program.

What version of the product are you using? On what operating system?
gnome-mplayer 0.9.9.2 on Fedora 12

Please provide any additional information below.
This happens ONLY when Caps Lock is activated. <s> takes a single screencap as 
it should, but <S> triggers the bug.
