I followed the instructions to enable testing packages and confirmed that, after doing so, Banshee was able to download episodes from the podcast cited in https://bugzilla.redhat.com/show_bug.cgi?id=1409665 and I was able to listen to two episodes (that's all I tried). The console printed:

[Warn  11:17:59.643] DosLineBreaks detected in xml
[Warn  11:17:59.646] UTF-8 BOM detected in xml

As the episode list was downloaded. Presumably, this means that there were two odd things about the RSS and Banshee has corrected both of them.

Unfortunately, when I tried other Podcasts from the same site (Cadena Ser: http://cadenaser.com/ser/podcasts/) they did not work. However, I believe these are failing for unrelated reasons and I plan to open a separate bug once I have done more investigation. Note that none of these worked before the fix, so this is not a regression.

Banshee continues to be "generally functional". I was able to do all of the things that I typically do: listen to MP3s from my machine, listen to some Internet radio sites, get updates for podcasts and listen to them.

Thanks for the fix!

I've noticed a few times in the past week that when I try to quit Banshee (Media -> Quit, not click the close button), the application becomes unresponsive and I have to "force quit" the application. That never happened before I started testing this change, but it could be due to some unrelated change to the system. I haven't been able to pin down any repro steps--it only happens after I've been using Banshee for a long time (mostly listening to podcasts and Internet radio).

I don't know how to gather any useful information, such as stack traces of running threads.
