[bug] Broken "Kill the Newsletter" feeds

[ckiyme]

Hello and thank you very much for this amazing app!

I just want to report a bug that occurs when try to read/access a post publish by a feed added using Kill the Newsletter.
What happens it's very simple:

• I open the app,
• I click on a new post,
• If the post's feed has been added via KtN, the Miniflutt freezes.

I've tested other apps and the issue doesn't occur, so it might be something specific to this app.

Please let me know if I can do anything else to improve this report.

Bump. This happens for me as well, but it's not every feed added via Kill the Newsletter, just some.

I can also provide examples of newsletters that work vs ones that don't, if that'd be helpful.
