-- Information about the crash:
As I was using Parley, it would add an increasing number of entries to the "correctly answered" tally (ie., 15 more after the 15th question I answered, 16 more after the 16th, etc.). It crashed when the number of "correct answers" exceeded the number of possible answers.

The crash can be reproduced every time.

 -- Backtrace:
