Bug Description

Binary package hint: indicator-session

I had to kill ubiquity, because it stuck at the bootloader installation and no button press did anything. After restarting the installer, this message appeared.

Interesting that this seems to be when checking with ConsoleKit to see if we can activate sessions, but after the GConf key changes. It would make sense that we've already checked once at that point. So there must be something happening to the proxy where it's non-NULL but not valid.
