What I always try first in these situations is: turn off garbage 
collection with GC.disable. If that stops the segfault, then it's a good 
bet there's a bug somewhere in the mark/free funcs within FXRuby.

Other than that, I would try paring down the app to the minimal code 
that will reliably cause the problem, and then post it here. Of course, 
that can be hard work....
