I had been using another desktop environment because KDE was too buggy... oh just now, something else crashed while typing this. So sad... I love KDE but it's not ready.
Please let me know what I can do to troubleshoot this. I am a humble sysadmin, but given enough instruction, I should be able to provide what is requited. Kate has become because I cannot open any files. I have turned off all compositing, and the issue remains. Please help me help fix this.

Yeah, I am running Kate out of another desktop environment and it's weird... it stays up in the background, doesn't start when you want it to, freezes randomly. I've gone back to VIM :-\ In this case, I set my desktop to "Folder view" then as I was changing my desktop wallpaper. I clicked on "select file". Plasmashell crashed. Then something else crashed in the background, while I was writing the bug report!! Don't know, don't care, I am not using KDE5 for now. I just logged in to check it out, and see how stable it was/would be. I guess my question was answered.

sudo dnf -y upgrade qt5* kf5* --enablerepo updates-testing --refresh qt5-qtbase.x86_64 5.5.1-11.fc23 @updates-testing qt5-qtbase-common.noarch 5.5.1-11.fc23 @updates-testing qt5-qtbase-gui.x86_64 5.5.1-11.fc23 @updates-testing No more immediate crashes! Thanks!!!
Sorry the correct command line doesn't require kf5*, thusly: sudo dnf -y upgrade qt5* --enablerepo updates-testing --refresh HOWEVER, something else (perhaps not this update, but this morning's) has broken kwallet5, but that's for another ticket.
