[reSIProcate] Exception can not be catched by a try/catch block

[Scott Godin]

Wow - that's strange.  Not sure why offhand the try/catch you inserted
would not catch that exception.  My guess is some kind of compiler
issue/option.  Does it matter if you try to catch Exception or
BaseException explicitly instead of the catch all "..."?
