Hi, the page of Computerteddy is a little bit confusing. I used the file world.tgz. After downloading planet_neu.tgz I could import the map successfully. So it seems that the data into the archive world.tgz is somewhat broken.
I digged a title bit deeper in the world.tgz and found the following. At CMapTDB.cpp the variables south contain the value -3.141593 and north -1.570796. As a result the following string "+proj=merc +lat_ts=-134 +ellps=WGS84" is passed to pj_init_plus. This results in a return of a NULL pointer and pj_errno is set to -24 (lat_ts >= 90) I am not sure, what are valid parameters, but at least the return value of pj_init_plus should be checked against NULL to detect broken maps.
