Comment 2 for bug 1361897

It was not raising one specifically, but I have seen it raise one about the gpg key. I dont remember specifically what the name of the exception was.

I think Gavin was just talking in general, it doesn't matter what exception, it will fail. Here is the review that this bug is referencing.

I think it would be nice to have a exception handling TimerService base class that just logs exceptions and keeps the timer service running.
