"Unexpected error during the game" in campaign select screen

[Benedikt Straub]

In my branch which has a 3rd and 4th frisian scenario, my campvis file looks like this after some testing:

frisians00="true"
frisians01="true"
frisians02="true"
frisians03="false"
frisians04="true"

In the campaign select screen, I chose the frisian campaign and was shown the scenarios 1, 2, 3 and 5 (as expected). I used the down arrow key to navigate, and when the missing entry 4 was reached, it should have gone straight from 3 to 5, but instead I got an error:

Unexpected error during the game
[../src/ui_fsmenu/campaign_select.cc:397] De Datei-Padd »« in de campaigns.conf is ungültig.
Bidde melle deeses Probleem, daarmit wi Widelands beter maken könen. Du finnst mehr Narichten över dat Probleem in de Normaal-Utgaav (unner Windows is dat stdout.txt). Du bruukst Versioon bzr8851[fri03] (Release).
Bidde melle ok deese Informatioon.
Widelands versöcht, dat Speel to sekern, wenn een Fehler bi’m Spölen uptreddt. Mennigmaal – nich immer – kannst du dat laden un wiederspölen.

Apart from the 'crash' that sent me back to the main menu, the information that the error occurred "during the game" and tried to create a savegame is also interesting…

I also get this error when I directly click on the last visible entry, so apparently missing entries are not correctly skipped…

I don't exoect that this is new, so I'm retargeting the bug. It might autofix itself https://code.launchpad.net/~widelands-dev/widelands/campaignselect_box because the design will be changed from visible scenarios to completed scenarios.
