Ekos INDI crash with Nikon D7000 camera

[Richard Ellis]

Using kstars flatpak stable V 3.8.3 and the INDI drivers supplied in 
the flatpak.

More often than not (i.e., sometimes it does succeed) Ekos reports that 
"indi_nikon_ccd  crashed!" when attempting to take a photo using my 
Nikon D7000 attached via USB.

I believe I have turned on all of the "debug" options, and captured this 
in the logs from the latest crash last night:

If I have overlooked any additional "debug" options, please indicate 
where to go to turn them on and I can repeat the crash again (it 
crashes more often than it is successful) to capture another log 
output.
