--- Comment #64 from Heiko zuxez@uni.de 2013-01-30 09:40:26 CST --- Btw, the qt-demo applications (EA's Qt-origin version and Qt upstream's ones) that are threaded and/or networked seem to work just fine under wine, so I'm unsure if I'd call it a Qt-problem or not. Though, they probably do not spawn as many threads as Origin does...
And that patch will only workaround network problems in Origin. The EAProxyInstaller hang still occurs.
