Not a troll but willing to take a bit of a stab.
If one is removing a widget from a layout it's generally to reparent it.
You needed to copy the line above the note.

Removes the widget /widget/ from the layout. After this call, it is the
caller's responsibility to give the widget a reasonable geometry or to
put the widget back into a layout.

A widget removed from a layout tends to not have a reliable geometry. If
one is going to delete the widget a better question would be, why bother
removing it. You have the pointer already so just do
widget->deleteLater();

So addItem parents it as it's own, then removeItem leaves it. No wonder it was
crashing. This might be a bug? I don't know why removing it would keep the
parent (the layout) then your subsequent call to delete deleted the widget and
it's layout, so the parent was left dangling. I would have expected that the
parent be nulled out, rather than keep it referencing the layout it had just
been added to and removed from. Perhaps a Troll can comment?
