In ModelTest.cpp:325ff it reads:
> While you can technically return a QVariant usually this is a sign of an bug in data()
Why is this? I normally return a QVariant() for data I do not have (e.g. if an item has no tooltip or icon, I return QVariant() for Qt::ToolTipRole and Qt::DecorationRole.
Is there something wrong or unusual about it?

That particular test is checking the data role: Qt::DisplayRole, which usually would return a QString.
The bug that this was made to find was cases where a developer would plug a new model into a view, only to find the view wasn't displaying any text at all.
There is nothing wrong with returning a QVariant() for the DisplayRole. Disabling this test or returning an empty QString are two ways to work around this report.
