Frederic Bouvier:

The create_dir was totally broken. No function was used at the right place
except mkdir. This patch now create directories without segfaulting.

Erik:

This was my bad, I've been using a really slow computer for the last ten months
and recompiling SimGear with a change to the properties code takes ages, so
once in a while I apply something not entirely tested. This is one really bad
example which shouldn't have happened. Thanks to Frederic for fixing it.
