I have encountered an issue which causes KStars to hard crash and leaves no useful info in the log. I've so far caused this to happen in two ways what appear to have caused some sort of corruption.
1. Using EQModGUI to move mount
2. Using the Sattracker script from the satellite tracking thread.
After either of those triggers KStars became permanently unstable. It will now crash whenever I make a track target selection in KStars. It does not matter if I am driving my real mount or Telescope Simulator.
Manual slew commands with the buttons from within EKos does not cause a crash.
I have tried reinstalling kstar-bleeding, and found it did not clear up the corruption.
My only recourse at this time is to reinstall my backup image and avoid those initial triggers.
