This crash is in a call like this:
  posix_fadvise (fd, 0, 0, POSIX_FADV_SEQUENTIAL);

posix_fadvice is a glibc function, and shouldn't crash, even if fd is
invalid (which i don't think it is). You might want to write a smaller
test case outside of gnome-vfs that calls posix_fadvise to debug the
issue further.
