Actually, it took some time but I finally figured it out. It would 
appear that GCC needs the type being thrown to have a virtual 
function table for it to pass across shared object boundaries. This 
is odd, because my base exception class never had a virtual function 
table and I swear it used to work.

However, I do do most of my testing on Windows (better debugger). So 
it's entirely possible I missed it.

Cheers,
Niall
