Has anything changed in the handling of style plugins between 5.8 and 5.9?

A few more lines of output later I now know that the stale sender object corresponds to the style instance which is delete'd (much) earlier than the call to QDbusConnectionPrivate::closeConnection() in the global destruction.

Yet we call `disconnect()` in the style dtor.

I'm a bit at a loss understanding why this would bite us only in very select applications. The only sensible explanation I see is that the app in question here (rekonq) hasn't been maintained for a few years and may never have been ported correctly to Qt5.
