Reference Issues/PRs

#433

What does this implement/fix? Explain your changes.

Some broken packages with empty .egg-info folder, will result in empty metadata, which will give None as pkg name and cause ValueError("A distribution name is required.") in Distribution.from_name

Added some simple filters to ignore them.

Does your contribution introduce a new dependency? If yes, which one?

No

What should a reviewer concentrate their feedback on?

Any other comments?

Thanks!

Is there any way to test this, e.g., with pytest patch or similar?
