Created attachment 1265408 [details] The downgrade that removed the problem Description of problem: Several months ago I installed the KDE spin of Fedora-24. I upgrade regularly. Minor problems. However since my last upgrade, plasma "crashes" during logout; downgrading plasma-workspace-libs (and others) removes the problem. Also reported in: https://bugzilla.redhat.com/show_bug.cgi?id=1211075 Version-Release number of selected component (if applicable): 5.8.6 (vs 5.6.4) How reproducible: Always (at least in my case) Steps to Reproduce: 1. login (gui) 2. logout 3. Actual results: "Session" does not close in an orderly manner; eventually the greeter shows again, but not after the appearance of an icon (in systray), telling me that "plasma closed UNexpectedly". Expected results: Log out; subsequently showing the greeter. Additional info: When I click the icon (systray), a small window (stack trace) appears, telling me that the crash occurred in NotificationsApplet::onScreenChanges(), apparently present in file: /usr/lib64/qt5/plugins/plasma/applets/plasma_applet_notifications.so.
Created attachment 1265816 [details] plasmashell-20170323-154530.kcrash.txt -- stack trace! When plasma (plasmashell) crashes, an icon (in systray) appears. Clicking this icon, triggers a small window, in which a "stack trace" is shown. After several attempts, I managed to save the stack trace.
Thanks, I think that helps. I have pulled in an upstream fix and doing a new plasma-workspace build now, to available for testing soon.

After these attempts, the output of "ps" shows multiple "/usr/bin/plasmashell --shut-up" with stat column indicating "Tl" (i.e. trace).

As far as I can tell, there must be a difference between the two ... Anyway, Rex thanks for your help/intervention! --
