Usually that happens after Tixati was running for a day or two, suddenly one of my rss feeds cannot be downloaded.
Opening RSS link in browser or other RSS client works fine.
Tixati needs a restart to make this feed working again
Error message :

starting update > RSS Feed
[19:56:15]  update failed: Error parsing feed: code 10 @ pos 2 line 0 col 2 > RSS Feed

I checked by downloading feed as raw bytes, there is a valid ascii character at line 0 col 2

So, is anyone looking into this bug?
p.s. I'd wish Tixati had a proper bug tracker

It's the traker offline or the rss feed is gone.
