Bug#677609: Reproduced here.

[Boris Bobrov]

> On a game (20 karts, me Adium, Farm, 4 laps) without presents ("time 
> trial?"), I did not see the error, but I did not try more than once.

It never happens on "time trial". I tried it multiple time with different 
number of AI carts.
It happens only when a present is used; not always after use, but sometimes. 
Which present - I don't know. It also happens not only with Adium.
