Broken feed with WordPress 2.0.6
Thanks to maxx and oliver for reporting a problem with the feed of my blog. rss2email displayed the following warning:
% e2run W: looks like HTML http://michael-prokop.at/blog/feed/
and whereas bloglines.com, Firefox, Internet Explorer, Awasu and even dog and wget worked without any noticeable problems there also was a problem with rss-reader akregator.
Finally I could track down the problem with:
% GET -e http://michael-prokop.at/blog/feed/
and use of telnet and stumbled upon ticket 3528 in the wordpress bug database then.
Conclusion: if you upgraded your wordpress installation to version 2.0.6 you might want to apply the fix mentioned in ticket 3528.
