Bugs I've noticed already:

At least one of my podcasts has messed up names for the episodes.
See this feed: http://www.democracynow.org/podcast.xml

Today's episode (Thursday) shows up second on the list, that is, behind wednesday.
The name of the episode is listed as a bunch of gibberish characters (most I can't type, the rest include OUM<}wN, etc.

Also, when viewing "today's episodes", canola locks up for about 45 seconds, the wheel even stops spinning. I ssh'd in, and saw that a python process was using about 90% of the CPU. It's fine that it has to go out and fetch updates, but at the least, it shouldn't stop the interface from spinning the wheel.
