Reported using DrKonqi
clicking through the pot. dupes, this seems fedora/64 related. bug is likely somewhere in Qt or dbus and likely triggered by the pending activity related dbus calls (hopefully resolved by kactivity updates)
@Ivan: please check whether that dbus error in KActivities still applies and close if not
If kwin is using a single instance of Consumer (and it seems to do so) the call to waitForFinished should never happen. Though, there might be some other issue since kactivities is not designed to be thread-safe. Closing. If it happens again iwth the 4.10, please reopen.
