I've found gpodder flakey to say the leasted.

For me, if I do anything else while the unit is downloading a podcast, even inside gpodder itself, then it hangs the unit terribly to the point of crashing sometimes. Also after leaving gpodder running overnight to collect podcasts with the scheduler I looked this morning to find gpodder had stopped running completely and was nowhere in sight!

I'm using a N770 which may have problems?
