[PyQt] How to expose function accepting array of struct to D-Bus?

[Evade Flow]

While attempting to put together a test case for this array-of-struct
difficulty I'm having, I discovered that I can't even talk to most of
these (C++/Qt) services using the standard dbus-python module. For any
method that takes an array-of-struct, I always get 'No such method'
errors.

Since this isn't PyQt-specific, I posted a question to stackoverflow.com
(see http://is.gd/dyhcNh). However, I figured some folks on this list
might be interested, or might know why a Qt-based D-Bus service that
exports methods with array-of-struct in their signature are (seemingly)
so darn difficult to invoke from Python! `:-}
