The return from gtk_file_selection_get_filename is a const *gchar.
So you should replace the declaration

gchar *ausgewaehlt;

with

const gchar *ausgewaehlt;

(You are implicitly discarding the "const" qualifier by assigning the
filename returned by the file selection dialog to a plain *gchar
variable.  You're not allowed to modify ausgewaehlt.)
