Adding wrong ware per script crashes game

[Notabilis]

When creating and filling a building per lua script, the game crashes when the ware can not be stored in the building.

Version: trunk/r8163

Steps to reproduce:
- Modify:
 data/tribes/scripting/starting_conditions/barbarians/fortified_village.lua
- Give the lime kiln "log" instead of "coal" as input.
- Start a game as a barbarian fortified village.

Expected behavior would be an ingame message about the error (as hinted by the console output and happening on other lua errors). Unfortunately, the game crashes while trying to do so.

We actually get these a lot with Lua programming errors, and it's sort of on purpose - we didn't halt these in the past and ended up with some bugs that nobody noticed for a good while.

It is still possible to unpause the game and continue playing, so this doesn't qualify as a crash.

Attaching a screenshot of the error message.

That is the message I was expecting to see (and have seen with other errors).

Ah, turns out I failed with the "steps to reproduce" (again...).
It only crashes, when the player is the only participant in the game. With some
AIs it works fine.

Yes, I can reproduce that when I deactivate a player in the setup screen.
