As a precision :
dbus_g_proxy_call() returns 0 but hash_table contains 0
entry.
It's maybe related to the fact that
props->device_file_by_id[n]
and
props->device_file_by_path[n]
are NULL => segfault
the "for" loop should probably contains something like :
props->device_file_by_id != NULL
and
props->device_file_by_path != NULL
(do_show_info, lines 1000-1010)
as it done with, eg, props->device_mount_paths.
(anyway it doesn't explain why I get NULL values everywhere)
