segv in indi gui

[Jasem Mutlaq]

Hello Hy,

I think I submitted a refactor of the INDI Control Panel in KStars
that should fix such crash-on-disconnection issues. This commit has
the fix: 678c5e360c7651060c65133ed97b074c0b24bc40

However, we must thoroughly test KStars now for stability issues.
Robert reported crashes on the MacOS client with INDI, so this needs
to be investigated. The due date for 3.5.5 was planned for September
6th (Yesterday) but I really think we should delay perhaps for a few
days until we ensure stability issues are addressed. Hopefully more
users would try the beta to report back. Keep using KStars with *real*
equipment under real conditions to catch some of these elusive bugs.
