remove a method

Hi,

I use Squeak 3.9#7067 and in one of my classes I would like to remove a method. 
In the last days I loaded several EToy-projects into my image.

Now, removal does not succeed and instead I get a 

MessageNotUnderstood: SmallInteger>>pragmas.

Looking at the trace I understand that there is a sequence of actions to 
determine usage of the method to remove in other classes. This sequence stops 
at the class "Player78" which is in the category "UserObjects". 
The check for "Player78" ends up in

CompiledMethod>>pragmas 

which returns ^self properties pragmas and leads to the MessageNotUnderstood.

What is the right thing to do ? What is happening exactly ?
