Right now all downloaded podcasts have only read permissions (for user, group, and other).  This means when you try to remove a podcast from Banshee, it doesn't go anywhere, leading to all kinds of cruft in the podcasts directory.

Downloaded podcasts should at least have user write permissions as well.   



Other information:
Changing the permissions to the directory itself does not change anything.  Any new podcasts downloaded after the change is made will still only have read access.

I searched for this in both Bugzilla (no luck), Launchpad (nothing) and Google (almost nothing for five pages, and I gave up).  I'm sure this has been addressed before; if there is a patch or some hack available, I'd love to know it.  As it stands, I'm getting tired of weeding out my feeds every couple of days.  My wife and I share an audio and video media partition, and between the two of us that thing is filling up way too quickly simply because Banshee doesn't actually remove what you tell it to remove.  So for now, we're using something other than Banshee for podcasts.
