at libkworkspace-4.11.19/libs/kworkspace/kdisplaymanager.cpp:493 493 QDBusReply<bool> canStop = CKManager().call(QLatin1String("CanStop")); This hangs for about 25 seconds before returning a non-isValid() QDBusReply. Manually calling the same method with qdbus org.kde.ksmserver /KSMServer canShutdown immediately returns: Error: org.freedesktop.DBus.Error.NoReply Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. (I don't know or really care why ConsoleKit returns this way, but it shouldn't cause canShutdown to hang.) Note: canShutdown blocks on every attempt to open the K-menu. Reproducible: Always Steps to Reproduce: Click KDE icon in panel Actual Results: Plasma and ksmserver both freeze for 25 seconds Expected Results: Immediately continued on
Oops, but the wrong qdbus command above. This is the one that returns immediately: $ qdbus --system org.freedesktop.ConsoleKit /org/freedesktop/ConsoleKit/Manager CanStop Error: org.freedesktop.DBus.Error.AccessDenied Rejected send message, 5 matched rules; type="method_call", sender=":1.2524" (uid=1000 pid=31770 comm="/usr/lib/qt4/bin/qdbus --system org.freedesktop.Co") interface="(unset)" member="CanStop" error name="(unset)" requested_reply="0" destination="org.freedesktop.ConsoleKit" (uid=0 pid=1897 comm="/usr/sbin/console-kit-daemon --no-daemon ")
