SUMMARY

I am trying to use Ekos with an INDIGO server. Conencting when all the devices are in disconnected state and the profile is not set to auto connect, I can successfully connect. Connecting devices slowly one by one, I can get everything online and Ekos seems to work as expected.

When Camera devices are in connected state (or get connected via auto connect) upon starting Ekos, kstars crashes.

Scenario: Cameras are in connected state already
