Bug#880990: widelands: Segmentation fault on loading a game

[Elena ``of Valhalla'']

Package: widelands
Version: 1:19+repack-4
Severity: grave
Justification: renders package unusable

Dear Maintainer,

I have installed widelands on a buster amd64 system and found the sad
surprise that it is no longer working: opening any game (tutorial,
campaign or game) results in a segfault with the attached output.
I didn't try multiplayer games.

Originally I tried with an existing ~/.widelands directory, but I moved
it away and could still reproduce the behaviour.

Please let me know if there is any other information I can provide: I
have all of the free time saved by not playing widelands that I can use
to help investigate this issue :)

The following are the last few lines of ``strace widelands``:
