Sentry Crash Report:

Description jusasi+kdebugs 2022-03-15 19:20:32 UTC 
Application: kstars (3.5.7 Stable)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 5.4.0-100-generic x86_64
Distribution: Ubuntu 18.04.6 LTS

-- Information about the crash:
- What I was doing when the application crashed:

Opened KStars, started Ekos, slewed to a star, went to align. With default solver settings (Internal SEP, Internal Solver, Default profile) I ran the solve. It ran the exposure, then crashed.

Looking at the stack trace looks like this is where it crashed:
StellarSolver::setIndexFolderPaths

At first I did not have indexes downloaded, so I thought maybe that's why. Then some indexes were downloaded and I ran it again, same crash. Also tried changing solver to Watney solver, no effect, still crashes.

The software versions I'm using:
libstellarsolver:amd64/bionic 2.1+202203102136~ubuntu18.04.1
kstars-bleeding:amd64/bionic 6:3.5.7+202203041042~ubuntu18.04.1 
kstars-bleeding-data:all/bionic 6:3.5.7+202203041042~ubuntu18.04.1 
kstars-bleeding-dbg:amd64/bionic 6:3.5.7+202203041042~ubuntu18.04.1

The crash can be reproduced every time.
