The present state is that Installer reads the proxy type from QSettings, but 
there is no gui to set it. Your patch does it so the problem should be solved 
after applying it. The second reason for keeping it open was that I have no 
feedback if it really has helped (with manually adjusted QSettings).

Probably we should create a very simple Qgs standalone application to determine 
whether it's a Qt bug or something in the implementation.

In fact, I still don't know whether Installer works with proxy, but I hope yes.

It doesn't use the QgsHttpTransaction (there is no Python bindings) and uses its 
own QPHttp object, which inherits from the QHttp and just applies the proxy 
settings to every instance when created. I hope your path for WMS + managing the 
QSettings is sufficient for both Installer and WMS. 

But there is also WFS remaining (and what with postgis?)

Unfortunately I don't use proxy so I'm doing that all a bit gropingly.
I can only say that your patch for QSettings seems to be fully compatible with
