[Observium] 'x' not working anymore in input fields

Hi

I've noticed this afternoon that I'm no longer able to enter the character 'x' or 'X' in any input field. Pasting the character works but not normal keyboard input. All other characters seam to work as before. A work collogue has the same problem. So I think it's not the browser. The new behaviour seams to be on one of the changes since Thursday. I had a look at them and can't see and thing suspicious.

I currently run svn version 4715.

Any Idea where to look ...

Regards

Matthias
