I had these strange installation problems (when it says there was an error during installation etc.) twice. Uninstalled, re-installed, hated the re-boots... This is lousy, really. The whole PR 1.2 experience is a mess.

Anyway, after the third attempt to install this thing it seems to work. I can at least call myself. (I initiate a call from my N9 with the Google Talk account online to my desktop PC where I'm online with a regular XMPP-account.)

The only thing I notice (I hate these small bugs) is that the smaller video on the N9 - the window that shows what the other party will see - goes black after a few seconds. The call still continues and my video is still visible on the other end of the line, I just cannot see what I'm showing to them at the moment.
