"Lua Coroutine Failed" as Inbox Message

[C. T. F.]

When playing the "territorial lord" mode (I used it in single-player mode) and you managed to get 50% of the land under your control, you have to wait for 20 minutes. At the end of the first 15 minutes there was a pop-up message in my inbox saying that there was a error in Lua.
The heading is "Lua Coroutine Failed" and the body shows me some additional information:

[/build/widelands-19+repacks/src/scripting/lua_error
[string
"script/win_conditions/territorial_lord.lua..."]:132
attempt to compare number with nil
(I think there is some more content in the first / third row, but it's out of the view)

It's weird that the player get such a message as inbox message (with the type "undefined").
I hope I was able to help somebody fixing it. ^^

Thanks for reporting!

It's this loop:

               if teampoints[t] > ( #fields / 2 ) then
                  -- this team owns more than half of the map's area
                  foundcandidate = true
                  if candidateisteam == true and currentcandidate == t then
                     remaining_time = remaining_time - 30
                  else
                     currentcandidate = t
                     candidateisteam = true
                     remaining_time = 20 * 60 -- 20 minutes
                  end
               end

line 132 in the current development version, so the bug is probably still there.
