Hi!

Yes, you are right. I got this issue not in syntax error, I get it on
a runtime error like this:

t = MyImage()
self.test("hallo")   #test takes an integer so this would throw an
exception.


Here you see, an object of the type MyImage() was created but its not
deleted. 't' is a local reference so how can I do that?


Thanks!
