Editor: Crash when saving a map

[kaputtnik]

First encountered with r8484 Release build. Then tested with r8506 (debug and ASAN):

1. Start Editor
2. Place a players starting position
3. Save map

Result with r8506 running gdb:

Thread 1 "widelands" received signal SIGSEGV, Segmentation fault.
0x0000555556cecf31 in Widelands::MapScriptingPacket::write (this=0x7fffffff8780, fs=..., egbase=...,
    mos=...) at ../src/map_io/map_scripting_packet.cc:90
90 if (map_fs->file_exists("scripting/tribes/init.lua")) {

Backtrace is attached, ASAN output will follow.

Forgot: I've successfully made a map with r8482, so the culprit is r8483 or r8484

[GunChleoc (gunchleoc)]

r8483 or r8484 are impossible as culprits, all that was changed there were translations and some sprintf placeholders in the options screen.

[kaputtnik (franku)]

Ah, sorry... i have made the map with r8482 of the road cursor branch. After merging trunk into it the crash happened.

Fixed in build20-rc1
