Do you know any more about the circumstances around the crash?

I see from the backtrace that it crashes when you press the "More Info" button. Does it tend to crash when clicking that button for any app in particular? Were you also installing other things at the time you clicked on that button?

i have always this issue when i click "More Info" button only with "Browser Web Firefox" in menu "Internet -> Web Browsers"..with other apps i don't have this issue...i don't install other things at the time i clicked on "more info" button.
