emacs aborts (almost always?) when pressing C-g in gnus group mode

[Timmy Douglas]

(I'm not on the list so please CC replies)

When I press C-g in gnus, emacs almost always aborts (pretty much
crashing). I'm not sure exactly why waiting_for_input is 1, or the
meaning of it being 1 at this instance.

This is really annoying because whenever I use gnus, I have to be
careful about not pushing C-g because it usually causes emacs to
crash.
