[PyQt] Catching Qt exceptions in PyQt

[Allen Bierbaum]

I don't know what you are doing wrong or what causes this, but I do
know that we see it all the time when trying to debug and it makes the
entire process very painful.  If you find any type of solution that
works so you can see the exception that is being thrown, please let me
know so we can use it.
