[Bug 959151] Re: QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.

[GreyGeek]

I am running Kubuntu 16.04 with the latest patches and Plasma 5.6.   A few days ago I installed KGpg and created a key.  It ran perfectly.  Then an update came down the pipe.   Now, I cannot start KGpg from my user menu or from a user Konsole.  The attempt aborts with the message
"QDBusConnection: session D-Bus connection created before QCoreApplication. ... "

Systemctl shows I have two dbus services running:
dbus.service                            loaded active running   D-Bus System Message Bus
dbus.socket                             loaded active running   D-Bus System Message Bus Socket


However, if in a Konsole I enter "kdesudo kgpg" it will start up and run as root.

Obviously this message is NOT a "harmless" and more than a mere nuisance
if it prevents programs from being run.  A LOT of these "nuisances" have
popped up on Kubuntu and other distros using both Plasma 4 and 5 for
over FOUR YEARS, and its not doing KDE's reputation any service.

KDE Neon is being built with QtQuick and QML and the bug has appeared on
it as well, as evidenced by previous posts.  That suggests that the bug
is in QDBusConnection itself.
