I am getting this too on my personal RSS feed. The reason is that the <description> field directly includes HTML tags, while they should be entity-encoded or enclosed in CDATA, if I’m understanding the spec correctly. “a b CWE-ou” is what my feed reader makes of those tags.
which, besides looking more like program code than English, is missing almost every piece of information I would expect: it doesn’t tell me which pull request he commented on (I would like the link of the entry to point to that, but it just points to https://bitbucket.org/) and it doesn’t tell me what his comment was.
I get the impression that this problem does not affect everyone?
