Check a pointer in skipdirs() before dereferencing it. I don't fully

understand why it can become a null pointer under some circumstances,
but i've got a pile of tapes where this happens, and running it thru a

thing.

Anyway, it cannot make it worse than now, where restore kills itself
with "Memory fault".
