while I don't expect amarok to handle a remote nfs server shutting down mid-stream perfectly, I think it might be able to be handled better then it currently is (Amarok freezes)

I appologize for the less helpful bt than usual, this is on my box that doesn't have debugging symbols built for most apps.
bt:
