I'm sorry. I did not realize that at the time parse_fuse_fd is called mountpoint could legitimately be a NULL pointer. This happens when gphotofs is run without arguments. As a consequence, the library segfaults there and the autopkgtest fails. parse_fuse_fd needs to handle a NULL pointer. Patch attached. Helmut
