- The function under consideration returns a QVariant, which is used internally within the C++ code. Sometimes, the value stored in this QVariant can also be a Python enum/Shiboken enum. When such a case occurs, the returned QVariant to the C++ side is a QVariant of Python /Shiboken enum, which cannot be processed from C++ code. - This is a regression from 108d82d2ca5323652a50706b37f829b9f0457367 which needs some special handling. - The solution is the convert the python enum (Shiboken enum) to the corresponding integer type, which is stored into the QVariant and returned to the C++ side.
