indi_canon_ccd segfault - by: noriQ

Hi.
I ran Ubuntu on Intel Stick PC and installed INDI server and Kstars.
However, indi_canon_ccd crashes with a segmentation fault.
The environment and INDI log are as follows:

system environment:
Ubuntu 16.04
kernel 4.10
kstars-bleeding 5:17.04+201707240921~ubuntu16.04.1
libindi1 1.5.0+r3264~201708021121~ubuntu16.04.1
