Description Flavius 2022-08-07 13:05:03 UTC 
SUMMARY
The only backtrace i get is "Segmentation Fault".


STEPS TO REPRODUCE
1. Open Kstars
2. Connect your equipment
3. Enable FITS Viewer in options and in the Processing section enable Auto compute HFR. With this option enabled, Kstars will crash everytime.
3. Use "Capture a preview" in Ekos' CCD tab

OBSERVED RESULT
Kstars will crash (sometimes it freezez on download).

EXPECTED RESULT
Open the image in the FITS Viewer and/or display it in Ekos' Setup tab

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Kubuntu 18.08
(available in About System)
KDE Plasma Version: 5.12.9
KDE Frameworks Version: 5.47.0
Qt Version: 5.9.5

ADDITIONAL INFORMATION
Comment 1 Jasem Mutlaq 2022-08-07 16:53:43 UTC 
Cannot reproduce this crash on KStars 3.6.0, can you please try 3.6.0 and report back?
Comment 2 Flavius 2022-09-03 09:24:10 UTC 
3.5.9 is the latest version i can find
Comment 3 Flavius 2022-09-03 09:44:11 UTC 
I started guiding using the simulator and this time I got a backtrace.

Comment 4 Flavius 2022-09-05 08:32:02 UTC 
sudo apt-add-repository ppa:mutlaqja/ppa
sudo apt-get update
sudo apt-get install indi-full kstars-bleeding

this always installs 3.5.9, not 3.6.0 as stated here: https://edu.kde.org/kstars/
Comment 5 Jasem Mutlaq 2022-09-05 08:44:19 UTC 
You might have old Ubuntu. Only 20.04 or later is supported.
