devkit segfaults in do_show_info()

I experience segault using devicekit-disks 007
(both gentoo ebuild of gnome overlay and from sources)

It probably stops in :
"for (n = 0; props->device_file_by_id[n] != NULL; n++)"
of do_show_info() in devkit-disks.c

The backtrace is helpless :
#0  0x0000000000403637 in do_show_info ()
#1  0x0000000000404be6 in main ()

0x000000000040364f <do_show_info+367>:	inc    %r12d
I can't --dump as it segfault after the "device-file:"
of the first device (sda)

Commenting both loops let's devkit-disks continue ... but ...
with NULL|0|no|01 jan. 1970|... values for all devices

dbus-monitor --system --monitor only throws two times :
signal sender=org.freedesktop.DBus -> dest=(null destination) path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameOwnerChanged
   string ":1.123"
   string ":1.123"
   string ""
Adding some debug infos I come into :

in device_properties_get() : call to :
g_hash_table_foreach (hash_table, (GHFunc) collect_props, props);
and in collect_props() I put a :
which does NOT appears (if you know about a way to debug there so
I can track this down ...)

Wish it helps
