Any ideas what this is about?
No traceback, just this message:
Exception RuntimeError: 'sys.meta_path must be a list of import hooks' in

Maybe I found it. I had an object managing my plot, which had a __del__ which
called pdf.close(). Probably this destructor was called too late. I now
explicitly call del on my object, and the problem is gone.
