Looks like you were connecting to a remote INDI in Ekos? Is this when the crash happened? Please take a screenshot of your profile.
Comment 2 Csaba Kertész 2017-07-03 08:04:11 UTC 
Please provide also any steps what you remember to reproduce this bug.
Comment 3 aluigi.teseo 2017-07-04 07:49:31 UTC 
After same day have this problem in night observation. I switch from kde to cinnamon ( from kubuntu 17.04 to Mint 18.2 Cinnamon ) ..no more problem no more crash, now i use kde only for kstars + indi ekos (this is amazing program).

Probably problem is from kde and not from kstars ( work very well in cinnamon Mint ) or possible problem is for my dated notebook? ( Acer Aspire Intel core i3 4GB ) Kde is too heavy for he?.

@Csaba Kertész
Problem was random without particular work, in much case just close a window ( preview image ) and crash all.

@Jasem
Profile is normal addittion of 3 device with "Indi Web Manager" in network with remote RaspBerry PI3.


All program described in problem is compiled myself from source.
Now with Mint Cinnamon 18.2 it seems ok.
