Segmentation fault after adding check lines

Hi again 
I'm currently trying to create a new track and have encountered a problem I cannot solve. I added a driveline to the track and it worked well (map, rescuing, etc.). Now I have added some checklines and SuperTuxKart crashes directly after starting the race, saying "segmentation fault" (or I hope so, language is set to german
). Can anyone help me? I'm not sure what I did wrong (or whether it is a bug).
And yes, the highway part will get lots of zippers
