Created attachment 1037360 [details] Fedora 22 packages updated on 2015-06-08 Description of problem: Unable to open KDE application menu. Dock is glacial if not unusable. Version-Release number of selected component (if applicable): kf5-kded-5.10.0-1.fc22.x86_64 How reproducible: Always. Steps to Reproduce: This problem for me started when I ran updates on June 8th, 2015. The main symptoms I'm seeing are 2x kwin_x11 processes running at near 100% and messages in the logs related to kded5 crashes. Actual results: KDE menu unusable; dock and all dock tools unusable. Expected results: Click on KDE menu, get a panel of launchers. Actions on the dock work. Additional info: This system was an upgrade from F21. This may be a config data issue with a user that was running KDE4. kded5 segfault may be unrelated to the high kwin_x11 cpu utilization and usability issue.

I strongly suspect a dup of bug #1228779 *** This bug has been marked as a duplicate of bug 1228779 ***
Confirmed: dnf downgrade plasma-workspace f22-kde-theme resolves the issue. No more segfaults. No more syslog messages. Thanks.
