Crash after first configuration, not starting anymore

[dreierhi]

Hello,

today I installed the prismatik_5.11.2_amd64.deb package on Kubuntu 17.04. After having selected the type of device (Adalight), the connection settings, and the number of LEDs (70), arranged in "cassiopeia" the application closed and every time I try to start it again I get the same message.

(process:2653): GLib-GObject-WARNING **: invalid (NULL) pointer instance

(process:2653): GLib-GObject-CRITICAL **: g_signal_connect_data: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed

I hope you can help me
