JS errors when adding a 2nd group admin or tryign to remove a group admin

Create a group (Closed). Invite someone to the group. Then make them an admin.

(On IE 7, but I think also FF), when you make a 2nd group admin you get two JS errors on the members page - JS Error line 376 and 399 "Unterminated String Constant"

After this , you can not remove a group leader.
