Not much should have changed between that commit and latest trunk, so it was no surprise that I was able to reproduce it in r6421. Note that this was a debug build, so it is not a release-only issue at least.
One thing which seems very odd to me is that I only seem to be able to reproduce this the first time I attempt it. Subsequent attempts, like reloading the savegame, or quiting restarting Widelands does not trigger the crash.
