[0.6.1] Crash when mining rail signal that is waited upon

[FrozenOne]

I mined the rail signal directly in front of waiting train. (Maybe there played a role that there was another train in the next segment). The game crashed.

Did it write some message?
Can it be reproduced?
Do you have save with the error?
There is some problems with rails, and we desperately want to find and repair it.

This one is pretty ordinary, just make 2 trains wait on both sides of rail signals, and then mine one of those signals between them. Instead of crashing trains, you get crashing game. No message.

I add the save, just mine the signal between 2 trains, it crashes without any message.

If you move one train a bit back, the crash occurs only if you mine the signal in the direction of waiting train.

Thanks for the report and the save. This will be fixed in 0.6.2.
