[pulseaudio-discuss] [PATCH] introspect: Fix a minor ABI regression introduced in 85e7fbc196

It seems that when converting to profiles2, the extra NULL terminated
profile object used in profiles was dropped. This caused regressions
in e.g. pavucontrol and kcm_phonon which relied on the previous
(documented) behaviour.

The above said, this *shouldn't* be needed as far as I can see.
The use of pa_xnew0 should initialise the memory to zero and thus
these variables should already be NULL. Issues have been reported
so the problem does seem to need fixing in some capacity:
