RuntimeError: OrderedDict mutated during iteration

It's a valid RSS feed: https://validator.w3.org/feed/check.cgi?url=https%3A%2F%2Fhabs.sdf.org%2Ffeeds%2Ftestfeed.rss

r2e works fine for other feeds I use, just not this one and I'm not sure why. Using r2e v3.9.

This was fixed in 60870d9ff. Time for a new release @wking?

Hello,

This repository has been deprecated for a few years now, and has been replaced by https://github.com/rss2email/rss2email .

If this issue is still relevant to you, and not fixed with v3.12.2, could you please reopen the issue there?

Cheers, Leo
