Crash upon toolbelt research completion

[goertzenator]

I happened to click on the toolbar just as toolbelt research completed. The research complete sound started playing, and then the game crashed a split second later.

- I reloaded the last autosave and then I was able to get past toolbelt research completion without crashing.

- I reloaded the last autosave again and tried to mess with the toolbar as toolbelt research was finishing, but I couldn't make it crash.

Version is 0.9.1

Cheers,
Dan.

This seems the same as: https://forums.factorio.com/forum/vie ... =30&t=2527 Which means it should be fixed for the 0.9.2 already.
