[Glass] Weird problem with class instance variable

[Dale Henrichs via Glass]

Mariano,

That is indeed odd behavior ... I would be suspicious of multiple 
versions of the class ... take a look at the oop of the class that you 
are sending the message to and the oop of the class you are inspecting ...

Other than that I can't imagine the cause ... one step at a time though:)
