Bug#982631: aborts on assertion failure at end of game

[John Scott]

Package: gnome-nibbles
Version: 1:3.38.1-1
Severity: normal

When you run out of lives at the end of the game, instead of showing
the scores or some more user-friendly behavior, the window immediately
closes with an assertion failure:

ERROR:linkedlist.c:1169:gee_linked_list_real_get: assertion failed: (index < this._size)
Bail out! ERROR:linkedlist.c:1169:gee_linked_list_real_get: assertion failed: (index < this._size)

The game feels rather pointless without being able to see previous
scores. Here's the backtrace:
