If it's fairly small I could take a look at it. I've never used Ruby's 
debugger and so I don't know if there are some inherent problems in 
using it to debug C/C++-based extensions like FXRuby. I hate to ask, but 
have you tried sprinkling a few print (puts) statements here and there 
to get an idea of which routine it's actually crashing in?

I doubt that re-installing FOX or FXRuby is going to fix this problem. 
Generally speaking, if the examples work OK then your installation is 
OK, sort of an all-or-nothing proposition.
