Confirmed in master as well. Not sure where these are coming from because the string "demo_tight_layout_00" doesn't exist in any of the version-controlled files.

The attached pull request resolves this issue. I am now going to upload a fixed version of the 1.1.x docs based on this change.

I think your fix would also solve a few other problems I have had as well (left over .pyc files get picked up sometimes), unless I am completely mis-understanding the regex.

I don't think it will address that, because it's only use with things before the extension. All it really addresses is that some of the examples produce multiple groups of figures, and those were not getting correctly linked back to the single .py that produced them.

Go ahead and file another bug if you're seeing something related to left over .pyc files.
