Subject: 30.1.90; gnus: wront-type-argument error when processing new nnrss
 group
Date: Fri, 29 Aug 2025 06:29:08 -0800

Hi. I recently added a new RSS feed to gnus, but immediately I am getting the error shown in the backtrace below. I imagine there is something in the feed formatting that nnrss doesn't like or wasn't expecting. This is the RSS feed I added:

https://alaskalinuxuser3.ddns.net/feeds/all.rss.xml

Here is the backtrace:
