simutrans r2119 GDI

When I loaded a very old game, simutrans crashed just after starting the game.

simutrans-.exe caused an Integer Divide By Zero at location 005979b9 in module simutrans-.exe.

Registers:
eax=000382a0 ebx=000382a0 ecx=00000000 edx=00000000 esi=08e0abb0 edi=00730070

Hmm, not easy to see why this could happen. Do you have the savegame in question?

Thank you.
It's not my game, so I send a PM.

Maybe fixed in next nightly.
