            Bug ID: 348840
           Summary: Plasma desktop locked, apps usable; log repeatedly
                    reports kded5 crash, metadata problems
           Product: kde
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: stefan_jones at comcast.net

History: I initially filed this as: 348772. This was set to a dupe of 347817; I
corrected the mismatch of kactivity versions. In fact, I entirely reinstalled
"KDE Plasma Desktop."

The problem recurred when I started up this morning (the first KDE/Plasma
session since reinstall).

Problem: Plasma is unusable. The task bar and screen controls simply don't
work. Task manager entries appear for already-open apps, but it and the other
widgets on the panel don't work. (curiously the digital clock widget does keep
time, so the panel isn't locked up.)

I can interact with the open applications. I had a xterm open and it is
available for checking logs and running queries.

I'm able to start and use Gnome with no issues.

This block of messages appears in /var/log/messages every few seconds during
the KDE session:
