Stellarium

In the case of Satellites class, the solution is to replace the
internal QList<Satellite*> satellites by QList<SatelliteP> satellite
with SatelliteP being QSharedPointer<Satellite>

I cannot reproduce it, but I had the same problem with other classes.
The problem is that your are not allowed to create 2 QSharedPointer
independently referencing the same pointer. When you click on the
satellite, apparently a new instance of QSharedPointer is created on
the real pointer to the satellite. The simplest way to fix that is to
use only QSharedPointer from the beginning, and never pass reference
to the pointer itself.
