1.13.25 segfault on -g

[mk]

Hi,

1.13.25 throws a segmentation fault in incremen.c when an incremental
backup is attempted and the user has no access rights for a subdirectory in
the list (seen on Linux with glibc-2.2.2).
The following simple change fixes it, but there is probably a more
elegant solution.
