[RAUC] Caught an error while installing bundle

[<caglar.kilimci@accenture.com>]

Hi all,

First of all thank you such an amazing product. I am really happy to found it.

I have been working on an embedded device which has barebox bootloader and would like to update via RAUC. I have successfully build rauc with meta-ptx layer and I can run rauc on device. In addition, I have created RAUC bundle in my development environment and copied into the device. Even if everything seems fine, I got below error when I would like to install bundle:
# rauc install update-2017.02-1.raucb

** (rauc:525): WARNING **: installer is NULL


(rauc:525): GLib-GObject-WARNING **: invalid (NULL) pointer instance

(rauc:525): GLib-GObject-CRITICAL **: g_signal_connect_data: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed

** (rauc:525): ERROR **: failed to connect properties-changed signal caught at main
Trace/breakpoint trap


I made small change to debug some but I could not go further:
