I can easily reproduce this problem with just M-x gnus RET, so I get
an infinite loop and can't use Gnus with the freshest CVS.
Due to the large size of .newsrc-dribble in older Emacs version I get a
question:
Buffer .newsrc-dribble undo info is 4823773 bytes long; discard it? (y or n)
but the latest CVS Emacs goes into an infinite loop:
