That message is not really an error, it is debug noise. If you
got that message, an exception was triggered, but then handled
correctly. If it hadn't been, you'd have gotten the familiar Oops.
If you care about fixing the program generating the exceptions,
the first number is the address of the instruction that faulted.
You can look this up in the System.map and find out what system
call the exception came from.
