Bug 461407

SUMMARY
Raspberry Pi 4 running 64-bit Debian 11, indi compiled using the astro-soft-stable script.
With a clean install, when clicking on the + icon to set up an optical train for the first time, kstars segfaults


STEPS TO REPRODUCE
1. Install kstar-3.6.1 on a clean raspberry pi 64bit Debian Bullseye installation, via the astro-soft-stable script.
2. Set up the following EKOS profile: eqmod mount, Touptek CCD, ZWO CCD, ASI filterwheel, MyFocuserPro2 focuser. (I don't know if it's specific to part of that configuration, this is just what I did.)
3. Start EKOS and connect to equipment profile.
4. Switch to imaging tab. Press the pencil button next to the optical trains dropdown.
5. At this point there are no optical trains shown in the optical trains dialog. Click the + button to add one.

OBSERVED RESULT
6. Segfault.

EXPECTED RESULT
Open UI to configure an optical train.
