[Vala] Vapigen failure for PanelApplet-4.0.gir

[Tal Hadad <tal_hd hotmail com>]

I try to generate vapi for PanelApplet-4.0(since vala don't include version 4.0), but
vapigen fails:
$ vapigen --library libpanel-applet-4.0 PanelApplet-4.0.gir

(vapigen:29191): GLib-CRITICAL **: g_str_has_suffix: assertion `str != NULL' failed

** (vapigen:29191): CRITICAL **: vala_gir_parser_node_lookup: assertion `name != NULL' failed
Gio-2.0.gir:44595.7-44599.24: error: `UnixSocketAddress' already contains a definition for `abstract'
Gio-2.0.gir:44475.7-44477.103: note: previous definition of `abstract' was here
Generation failed: 1 error(s), 0 warning(s)
$ 

Why it fails?
My valac is 0.14.0-1, in Debian wheezy.

Can someone please test it in his machine?

Thanks
