It's hard to say what might be going on here.  However, I would check a 
couple
of things.   First, make sure that the %exception code is actually 
showing up
in the generated wrappers.   The fact that you defined the exception 
handler
in a namespace like that might have some adverse effects (like only 
attaching
the exception to declarations in that namespace).    If, for some 
reason, the
%exception code is missing, that would explain a crash.   It's also 
possible that
there is some kind of linking problem.   Double check the 
compiler/linker flags and
make sure that exceptions are enabled or compiled properly.  I know on 
earlier
compilers, you sometimes had to specify extra options to make 
exceptions work
correctly with dynamically loadable modules.

Cheers,
Dave
