C GTK+: String returned by gtk_file_chooser_get_filename gives segmentation fault
 
My program gives a segmentation fault when fputs 'ing the filename. Why is that? ( fopen works like a charm )

Code:
void change_port ( void )
{
    if ( port != NULL )    fclose(port);    //    If it is already open close it

    char *fname = gtk_file_chooser_get_filename(GTK_FILE_CHOOSER(port_select));


    fflush(stdout);

    port = fopen(fname, "r+");

    if ( port == NULL )
    {
        error("Error Opening Port: ");
        error(fname);
        error("\n");
    }
}

void error ( char *msg )
{
    fputs(msg, stderr);

    fflush(stderr);
}
