In Debian Wheezy with accountsservice 0.6.21-6 GNOME 3 crashes [1][2] due to the patch applied in commit 5e2f077e [3] lib: manage pending consolekit calls with cancellable Pending NewSession objects can disappear just as quickly as they appear in response to ConsoleKit signals. If we're in the middle of talking to ConsoleKit when an object disappears and is subsequently freed, then we'll still try to access it from the reply callback. This commit cancels any pending messages to the consolekit daemon, when the session goes away. https://bugs.freedesktop.org/show_bug.cgi?id=50112 to fix bug 50112. It would be awesome if you could take a look. Josselin Mouette found the reason for the crash already. It would be awesome if you could suggest a fix.
