I tried the latest update .188 with the following feed that threw errors in MC revision .183:
http://www.onthemedia.org/index.xml
The error message reads:
This podcast feed is not currently available, or contains a data format error. Please notify the webmaster, or just check back later.
XML Field Error: channel tag = pubDate value = Fri, 23 Jun 2006 24:00:00 GMT
This feed still throws the same error in .188.
I suspect this is a boundary value condition where the current logic doesn't know what to do with 24:00:00 (is it 00:00:00 AM or 00:00:00 PM)? And it's arguable that 00:00:00 ever occurs.
I don't mind contacting the webmaster but what exactly should I tell him/her? Tell them to reference RFC822 date formatting specification?
FeedDemon, iTunes, iPodder (aka Juice) and NewsGator handle this feed without issue as I expect others do. I also suspect the webmaster may possibly push back given that other aggregators are not having issues with their XML file.
