Interesting.  This error is generated when you load two versions of the same 
class, outside of developer mode.  It's possible that you're actually loading 
the same version of the code twice, but NSBundle should be preventing this.  As 
far as I can tell, there is only one definition of GSColorSliderCell, so this 
error is a bit strange (and may be a libobjc2 bug) - can you check in a 
debugger whether the GSColorSliderCell class is loaded before you click on an 
NSColorWell?

You won't see this problem with old libobjc2 (including the 1.1 release) 
because, like GCC libobjc, it just replaces the old version with the new 
version and lets you deal with the potential memory corruption later.
