Crash when calling core.wait(...) from startup.ssc

[Matthew Gates]

To replicate:

$ mkdir ~/.stellarium/scripts
$ echo "core.wait(2);" > ~/.stellarium/scripts/startup.ssc
$ stellarium

Relevant output:
QPainter::begin: A paint device can only be painted by one painter at a time.
QPainter::setRenderHint: Painter must be active to set rendering hints
QPainter::setRenderHint: Painter must be active to set rendering hints
QPainter::worldTransform: Painter not active
QPainter::save: Painter not active
QPainter::restore: Unbalanced save/restore
QPainter::save: Painter not active
QPainter::setWorldTransform: Painter not active
QPainter::setOpacity: Painter not active
QPainter::opacity: Painter not active
QPainter::restore: Unbalanced save/restore
QPainter::save: Painter not active
QPainter::setWorldTransform: Painter not active
QPainter::setOpacity: Painter not active
