Apparently konqueror starts all programs in the user's home directory,
not in the directory where the program is. This is generally good,
because normally you don't stuff your data into a program directory (you
don't want to end up with the same bloody mess like on Windows).

You could try looking at argv[0]. Although this method is generally
considered unportable, unreliable and whatever, it seems to work here
with Konqueror (didn't try with Nautilus).
#include <stdio.h>
int main(int argc, char* argv[])
{
char cmd[1024];
sprintf(cmd,"xterm -e 'echo \"argv[0]: %s\"; read'",argv[0]);
system(cmd);
}
