[Pkg-utopia-maintainers] Bug#562068: [PATCH] linux/probe: don't use error prio init

[Sebastian Andrzej Siewior]

it may happen in the out: case that LIBHAL_FREE_DBUS_ERROR (&error) is
called before the error structure is initialized via 
dbus_error_init (&error). This could lead to a segfault during startup
as seen in dmesg:

|Intel AES-NI instructions are not detected.
|padlock: VIA PadLock not detected.

What I run into seems to be reported as Debian #562068 [0]. This patch
makes the segfault go away on my machine.
