Comment 48 for bug 744812

(Chatting to Saviq in IRC). We've tracked down some more aggravating factors. Main one being the Qt requests Medium by default(!) (in spite of having no internal Enum/handling for Medium).

Somewhat larger patch idea (blind, since I haven't rebuilt Qt), with substantially more comments. This includes both the ideal codepaths for the future, and minimal solutions separated by #if/#else constructs.
