I'm not able to reproduce that, using a nntp group from gmane -- can you
give me more detail about how you trigger it?

Unfortunately, the last round of changes might have left some cruft in
your .newsrc.eld file, if you had groups with non-ascii names. If you've
got some of that cruft in your group list, I suppose it's possible that
trying to kill a group might enter some sort of loop...
