I've seen similar problems posted previously but don't see a solution.
I just updated my OS from ubuntu 18.04 to 20.04 and since doing this. Kstars crashes just after capturing an image in the align (solver).
Possible some conflicting versions of libraries that do source extraction.

Back trace pasted below. Would anyone know what I've done wrong? thanks
