I can't say i've had the same problem, but without steps to reproduce i think this is going to be near impossible to pin-point.
The rythmbox database is locate /home/$USER/.gnome2/rhythmbox/rhythmdb.xml . It is possible that the xml file has become malformed; you may be able to recover your feeds by looking through it. However unless this issue gets some "me to" i don't think we can consider it a bug at this stage. -- [feisty] rhythmbox toss out all my podcasts subscriptions https://launchpad.net/bugs/85005 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
