[Bug 728595] [NEW] polkit-kde-1 crashes randomly on logout

[Romain Perier]

Public bug reported:

Binary package hint: polkit-kde-1

Sometimes polkit-kde-authentication-agent-1 crashes on logout, look at the backtrace.
Apparently PolkitQt1::Agent::Session is called twice, which calls Session::Private::~Private() twice , resulting in a segfault due to g_object_unref() (try to get the reference from an already freed object).
Basically I think a workaround would be check if Private::d is already deleted. This is a workaround because technically a destructor should not be called twice, It does not make sense. (my interpretation may be wrong)

We should probably report this bug on upstream.
