I imagine you're getting a negative integer from styleHint(), where
QColor.fromRgb() expected an unsigned integer. It should be possible
to add 2^32 to any negative values to obtain a suitable unsigned
integer for use with QColor.fromRgb().

Maybe this case could be handled by adding an extra overloaded fromRgb()
function to QColor in sip/QtCore/qcolor.sip that accepts negative integers.
