Aggregator 5.0 (and 4.7) not recognizing feed that works fine in 4.6

Cannot confirm - the feed works just fine with CVS HEAD.

I'm seeing this also in 4.7.x-dev on a site freshly upgraded from 4.6 to 4.7.x-dev. At first I thought it might be a problem with feeds not being in UTF-8 as was being reported here, but it is happening with all my aggregated feeds which were working quite happily under 4.6 aggregator. However I verified one of the problematic feeds and it does indeed appear to be in UTF-8: Science Blogs combined feed.

I'll try to see if I can't run down what's going on tomorrow.

Changing status to active.

I'm having the same problem with my uofl news feeds. I'm on drupal 5.0. Feeds that work in most readers don't work for me. Some days many of the feeds are broken but one site (http://www.courier-journal.com/apps/pbcs.dll/section?Category=cust01) 's feeds are always broken in drupal, though they work in every other reader I've tried.

The cron error says:
The feed from Louisville Courier-Journal seems to be broken, because of error "no element found" on line 1.

There doesn't appear to be an extra space in their feeds at the top... I don't know what's up. This seems like a drupal bug.

I saw a tip on another feed that worked for me. Submit the rss feed to feedburner and then use the feedburner url for your drupal. It's not the greatest, but it worked for me at www.uofl.info

Marking as duplicate. Let's paste all problematic feed links into one thread at http://drupal.org/node/127224
