[Qt-interest] QVariant::save: unable to save type X

I'm probably misusing or misunderstanding something here. Basically,
I've got a class with a public enum (FillType) that is used as a
Q_PROPERTY. Great - works fine. However, when writing that property to a
QVariantMap and writing the map to a QDataStream, I get the following
warning. (Self-contained 50-line example program of this problem attached.)
QVariant::save: unable to save type 258.
And the resulting variant, while having the correct type, lacks the
correct value:
QMap(("fillType", QVariant(AbstractVisualItem::FillType, ) ) )
The odd thing is, if I comment out the following line (line 31 in the
attached source):
qRegisterMetaType<AbstractVisualItem::FillType>("AbstractVisualItem::FillType");
It works perfectly! No warning, the variant saves the value for the enum
- it's all kittens and sparkles.
So, am I misusing qRegisterMetaType or is this a bug? A one word answer
saying something like, "misusing" is just fine - I just want to know if
I'm wrong or right.
Thanks!
