I'm not an ox-rss user and don't know if there are more realistic ways
to hit this error, but I was able to trigger it by taking an already
exported buffer of
--8<---------------cut here---------------start------------->8---
* h1
:PROPERTIES:
:ID: 76841adc-b233-4f6d-8446-3478f263544b
:PUBDATE: <2021-01-10 Sun 17:46>
:END:
--8<---------------cut here---------------end--------------->8---
and then setting PUBDATE to an empty string and exporting again.
I'm not sure if the error you see is indicative of a larger issue,
though either way guarding against an empty string as your patch does
seems fine. But...

... you're missing a closing parenthesis here.
Also, a bit downstream I see
(if (not pubdate0) "" ;; Skip entries with no PUBDATE prop
It seems like this should be updated to look at pubdate rather than
pubdate0 to avoid "<pubDate>nil</pubDate>" for the empty string case.
What do you think?
