Problem with QGamepad COM initialization on Windows

Running any QGamepad/QGamepadManager code I get continuous (i.e. every 5 seconds or so) repeats of messages like:

onecore\com\combase\objact\objact.cxx(834)\combase.dll!00007FF8BA71C7F7: (caller: 00007FF8BA71BB76) ReturnHr(1) tid(3c74) 800401F0 CoInitialize has not been called.

Aside from just being annoying it makes debugging my own code problematic, as many times debug output I want to see is obscured by these messages.....

This occurs in our own code or any of the QGamepad sample programs. Adding a call to CoInitializeEx() in main() and adding ole32.lib to LIBS in the .pro file seems to solve the problem.

I would've assumed this should all be handled by Qt += gamepad in the .pro file.
