It seems the bug was caused by a library call in
src/libes/gis/find_file.c. A string was copied to an empty string wich
caused the segfault.

The solution (or: my solution) is the following diff for find_file.c. I
can submit it to the CVS but I don't like to mess with libraries and I
don't know if there is a 'philosophy' behind the original method.
