I found a way to read and write the entries. It was simple and I don't know 
why the idea didn't occur to me sooner, despite the two hours I spent thinking 
about it. To write the entry, I only needed to pass write_entry a Qt::Variant 
created from the value using Qt::Variant.from_value. To read it back, I needed 
to convert the default value to a Qt::Variant in the same way and pass it as 
second argument to read_entry. This way read_entry returns a Qt::Variant from 
which I get the value using Qt::Variant#value.

I'd still like to know if there's no way to do this without the intermediate 
Qt::Variant.
