journal[2993]: Failed to store clipboard: Format UTF8_STRING not supported

Not sure what is causing the message or why the UTF8 not being supported. Generally scan the log now and then, so never saw this before??

Also, see this, but it is only a few?

clipit-startup.desktop[3331]: Clipboard is null, recovering ...

What desktop are you using?  It seems, you're using clipit as the clipboard manager?
