With my Fedora22 that has KDE5, I am using the awesome window-manager. Since the updates on November 14th (update of systemsettings5 was part of it) I am encountering several problems, that seem to be connected to the loading of my systemsettings at the system-startup. The failure to load network manager applet is just one of them. Further I cannot launch KDE applications like kshutdown or konsole, nor can I alter the startup/shutdown services (saying that KDED cannot be contacted), which results in not loading may Power Management profile.
You are probably talking about KDE graphical frontend (plasma-nm), because nm-applet is not run in KDE by default. https://wiki.archlinux.org/index.php/NetworkManager#Graphical_front-ends

I had it set to run at startup. However, this is not a problem anymore, and it seems to have been solved with a recent update (sometime last week). My systemsettings for the startup and shutdown services are now accessible and I do not get an error regarding KDED. Anyway, I do not think that this was a problem with the applet in itself, but rather it had to do with the loading of the startup/shutdown settings at the beginning of a session. The problem is solved now. Thanks, Sona
Fwiw, plasma5 only recently (re)gained support for classic xembed-based systemtray icons Closing per "problem is solved now"
