As said before, I have no experience with such .egg files.  But I can 
imagine (again, I"m not sure) that the debugger "knows" it steps into 
.py or .pyc files, so if it "sees" it will step into .egg files, ignore it.

I don't know the ins and outs of the Python debugger in Eric4, it's just 
a hint.  Having an error and being kicked out (like it is the case now) 
is also not an option to me...
