Ubuntu 21.04 5.11.0-25-generic, AMD64 plasma-desktop 5.21.4-0ubuntu1 Qt5 5.15.2+dfsg-5ubuntu1 Crashing in QGuiApplication::screenAdded() I bet the missing symbol says it's in QScreen::name(). If I'm right, I believe this is an upstream bug in Qt whereby sometimes the name of a newly-added or removed screen is empty and it crashes trying to retrieve it. Reminds me of https://bugreports.qt.io/browse/QTBUG-42985, though that was supposedly fixed ages ago.

I compiled kstars locally, and the bug did not occur. I suspect this is an issue in the PPA build. Please check against KStars 3.6.1 and report back.
