Bug#740340: tutorial lua script fails when building roads

[chrysn]

Package: widelands
Version: 1:18-1
Severity: normal
Tags: upstream

in the tutorial game, the player must build military buildings, and when
they are finished, the tutorial proceeds with introducing mines.

if the player stays in road building mode after building the military
buildings, or if he is just building a road to an additional military
building, and the tutorial takes control to build a road into the
mountains, it is (unexpectedly, to the tutorial script) not presented
with the build menu, but with the road building menu (consisting of only
a red 'x' to abort road building), and fails with a in-game message "Lua
Coroutine Fa...":

[/tmp/buildd/widelands-18/src/scripting/scripting.h:42] [string
"map:init"]: 132: attempt to index local 'panel' (a nil value)

after that, the game does not react any further, and can only be closed
as a window.
