Three days ago I did an update to the then-latest KStars (3.3.8_899_gd6a60f19d, self compiled from git) and did a successful observing night with it.
Today, without further changes, it crashed dead just by starting it. Running in gdb reveals
Thread 1 "kstars" received signal SIGSEGV, Segmentation fault.
0x0000555555bb01cd in SkyObject::translatedLongName (this=0x555558e874c0)
at /usr/src/packages/BUILD/kstars/kstars/skyobjects/skyobject.h:171171 QString translatedLongName() const { return i18n(longname().toUtf8()); }
BT suggested something during drawing of the sky view, but it was delayed a bit. So I tried changing the pointing before it crashed (click in map and move the mouse), and that prevented it from crashing.
Since then it's running fine. But maybe some Dev has an idea what might have gone wrong there? Attaching the logs, just in case...
