[r2870] Simutrans-Experimental savegame cause crash on "Load" dialogue

[z9999+]

r2870 GDI, MSYS+MinGW

If there is a Simutrans-Experimental savegame in save folder, simutrans will crash when I open "Load" dialogue.

But I can open "Save" dialogue without problem.
And also no problem with open/save bz2 savegame.

sim.exe caused an Access Violation at location 7c95b21a in module ntdll.dll Writing to location 10009740.

Registers:
eax=10009730 ebx=00000000 ecx=00000000 edx=061b6528 esi=061b6528 edi=00000000

I did not manage to compile bzlib with Visual Studio. The lib-files from gnuwin at sourceforge crahs simutrans while reading settings.xml :( any help appreciated.

I use the mingw files for GCC and the home compiled ones for VSC++ 5.0, and both work fine.

Strange. Any Simutrans-Experimental savegame cause crash for me.

Problem will happen when I open "Load" window from "New Map" window.
Problem doesn't happen when I open "Load" window from "Options" window.
I don't know difference between, but 100% reproducible.

I crashes from me only using the save dialoge. I know why, omitting one time closing the BZ2-Lib correctly causes all strange stuff. Will look into this today evening.
