seg fault while opening maps

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Setting OZEX_LAT and OZEX_LON inside the area covered by a map
causes ozex to crash at startup with segmentation fault. If OZEX_LAT and 
OZEX_LON points to outside the area coverded by map - ozex start OK, of course 
no map image is displayed.
2. Test done without gps device, OZEX_USE_LOG set to 0
3.

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?
Ubuntu both 32 and 64 bit

Please provide any additional information below.

First thought that it depends on Map Datum - I had o lot of maps in Pulkovo 
1942, but further test with maps in different datums gave same effect.

After some more tests: it depends on ozf2 file, sometimes ozex (and swampex) 
crashes with segmentation fault, sometimes it opens the map. It seems like some 
ozf2 files do not follow the specification (or the specification is not 100% 
correct).
