RSS feed widget bug

Hello and thank you for taking the time to read this.

I have seen similar posts in this forum but so far no solutions have been offered.

I have a k2 blog at https://halcyonrealms.com and am running on wordpress 2.2.

I am trying to post another blog’s rss feed on my sidebar using the RSS feed widget, but I believe a bug is present and some feeds simply refuse to parse, even though the feed is in perfect working condition.

An example is this feed :

Can anyone take a look at this ? Any help will be much appreciated.
