Tom Tromey 83b645b833 avoid python exception in FrameDecorator.py 
This fixes a bug in FrameDecorator.py.

FrameVars seems to assume that Frame.block can return None if there is
no block.  However, it actually throws an exception.

I saw this bug while developing a frame filter, but unfortunately I
don't know how to reproduce it.  It seems to me that the SAL tests in
_is_limited_frame should exclude the bad cases; and in my attempts to
write a test they do.

Nevertheless I think the fix is reasonably obvious and ought to go in.
