Bug#627349: gnome-dvb-daemon crashes if miredo is active

[Jochen Friedrich]

Package: gnome-dvb-daemon
Version: 1:0.1.23-1
Severity: normal
Tags: patch

If miredo is configured, gnome-dvb-daemon immediately crashes on start.
This is due to a missing check for NULL of ->ifa_addr in vapi/cstuff.c.
According to the man page (http://www.kernel.org/doc/man-
pages/online/pages/man3/getifaddrs.3.html), this field might be NULL in certain
cases, like the miredo interface which doesn't have a hardware MAC address.

This patch fixes the issue for me:
