The problem is with this line:
def create(self, name='file', addPlace2dTexture=True):
>>>> self.create(name=name) <<<<<
It's calling itself, creating an infinite recursive loop.
What you want to do is call the parent class's implementation. There
are two ways to do this:
texture.create(self, name=name) # Explicitly invoke
parent class by name
This will work, but means you will potentially have problems if you
ever change your inheritance hierarchy...
super(file, self).create(name=name) # Use super to find
next class in mro (method resolution order)
This is the more general way - it uses super to find the next class in
the mro. Unfortunately, you will potentially have problems if you use
multiple inheritance - see http://fuhm.net/super-harmful/ for full
details.
