Reported using DrKonqi
Comment 1 RD Beck 2020-02-07 21:18:37 UTC 
Created attachment 125758 [details]
New crash information added by DrKonqi

kstars (3.4.0) using Qt 5.12.4

- What I was doing when the application crashed:

KStars starts fine.  The crash occurs when I start INDI server, no devices connected.  Not all devices in the profile are presently attached.

Happened on consecutive startups.  Can sometimes be non-repeatable.

Comment 2 Flavius 2020-02-07 21:50:05 UTC 
my workaround for this (which started to happen after the last update) is to select the simulator, connect then disconnect and select my profile.
Comment 3 Jasem Mutlaq 2020-07-26 18:26:18 UTC 
Please test again on 3.4.3
Comment 4 RD Beck 2020-07-26 19:15:19 UTC 
Seems to work fine in 3.4.3.  

I started KStars and then EKOS.  I attached my arduino-based Moonlite-command set focuser, my arduino-based SQM and each of my ASI cameras and filter wheel with no issues.
Comment 5 RD Beck 2020-07-26 19:16:19 UTC 
By attached on the previous comment, I meant connected in EKOS.
