Subject: df: Fix segfault when using virt-df -a filename
X-Git-Tag: 1.7.18~6
X-Git-Url: http://git.annexia.org/?a=commitdiff_plain;h=fdc8805362c6fc587bb7985c5290362ad3094f4e;p=libguestfs.git

df: Fix segfault when using virt-df -a filename

If 'filename' doesn't contain a '/' character then virt-df
was calculating NULL as the basename and later segfaulting.
