Are you sure those .pyc files are correct?
I believe Zope doesn't normally write .pyc files for external methods.

Fortunately, that is not possible :-)

You could have the ext. method return str(REQUEST) as part of its output.
Maybe also self.getPhysicalPath() which should tell you something
about the calling context.

You do realize that's three years old, right?
It is certainly possible that this is an old long-solved
bug, but I have no knowledge of that.
