[0.12.4] Multiplayer crash when launching rocket

[Dr_Deadmeat]

I just played through the game and when I launched the rocket and got the "Game finished" view the server just crashes with a stack trace. The server is launched from a debian jessie box with the x64 binary and I ran the game from windows 10 x64.

To reproduce this issue all you have to do is run factorio from a server (I used the arguments "--start-server Andreas_Free --latency-ms 34 --autosave-interval 5 --autosave-slots 5") then enter that game, find the rocket launch pad and click launch. The server will crash and you will drop out when you get the victory dialog.

Oh, and by the way. Thanks for an awesome game I have just played way to much of it these past 2 weeks and probably will continue for a long time ^^

Thanks for the report, this bug is already fixed for 0.12.5 (which should be released today).
