[Pharo-users] How can an object have its "self" and "name" instance variables nil after being instantiated?

[Julien Delplanque]

Hi,

I have an object that override KMCategory and that is initialized and 
added to "KmRepository default" using #postLoadDoIt: message in 
BaselineOf after the package is loaded in an image.

But once it is loaded I have huge problems with keyboards entries, they 
do not work any more, I get an exception each time I press a key.

If I inspect the Singleton class variable of my category object I can 
see it contains an instance of my object that have its "self" variable 
nil and its "name" variable nil. Others variables look fine. How is it 
possible?

I can remove my custom KMCategory by copy/paste code from sublime text 
to Pharo and left click/do it and then everything is fine with my 
keyboard: no more exception and it behave correctly.

Thanks in advance,

Julien
