I'm unable to reproduce this on the current trunk -- exiting from `G G'
groups works fine here.

Your backtrace seems to imply that 

(gnus-info-marks group-info)

is nil -- is there anything special about the group you're searching?

(Are you setting "Mail-Followup-To: bug-gnu-emacs@gnu.org"?  That makes
the CC not contain "49866@debbugs.gnu.org", which is confusing.)
