Yes, that sounds exactly like it. In fact, I've also experienced the
additional problem described in the third comment there about the race
condition.

I've tried the "systray-simpler" application attached to the bug and that one
displays icons correctly, presumably because it uses QSystemTrayIcon directly?

I've also tried to update qt to 5.5 using the OBS project KDE:Qt55. At that
point, I had no more klipper but kmix still showed the same problem.
