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. |
