Re: [Rubycocoa-talk] Intermittent dump - problems in mouseDown()/NSNotificationCenter postNotificationName:object:userInfo:]

[Allison N. <dem...@ma...>]

Hi Brian,
In my (admittedly limited) experience with RubyCocoa, the bug most  
likely to make the internals of Cocoa blow up is when you hand Cocoa a  
Ruby Object that has been generated by a factory class.  My personal  
favourite of these is objects generated by YAML, but I'm sure there  
are others.

Is your problem always associated with NSNotificationCenter?  How are  
you generating the observer objects?  Can you post that code?

Hope that helps,

Alli
