I have got the first 2 back in again and it seems still to work, so I guess you are exculpated. That leaves only the debugger patch or my own fat fingers.
don't want to be sarcastic at your fingers, but I don't see how a fix in the debugger could change the way an app work when the debugger is not launched... did you try to run the app with the debugger started before the crash to see where you get the first fault ?
A+
