I've had a very similar sounding problem in a pure Objective-C app.  
Basically what happened was I didn't #retain something I should have  
#retain'ed.  I'll note that at first I thought it was in the  
libraries too, and had similar issues to what you had attempting to  
debug it. I don't know how you'd go about doing that from RubyCocoa-- 
theoretically you shouldn't have that problem in the first place.
