Reproducible: Always

Steps to Reproduce:
1. exit -> sleep mode
2. wait for machine to suspend
3. wake up

Actual Results:  
I'm getting notification window, which says that kdeinit5 crashed and I cannot post this error because there is no bug tracking address for kdeinit.
Then some tray icons dissapears (keyboard layout and audio volume as example) and there is no way to bring them back.
Only KDE restart (logging out or reboot) solves the problem.

Expected Results:  
Waking up without any problem

fedora 22 is up to date (updated 23.12.2015 from stable updates repo)

$ kdeinit5 --version
Qt: 5.5.1
KDE: 5.16.0

Comment 1 Kai Uwe Broulik 2015-12-25 09:58:57 UTC

Someone was spawning a notification as a passive popup and when it closed it crashed. Can you see a notification (a Plasma style notification, no DrKonqi)?

Comment 2 Martin Klapetek 2015-12-29 19:24:09 UTC

Setting as needsinfo.

Comment 3 nikita.rogatnev 2016-01-13 08:22:05 UTC

When I resume from sleep mode I don't see any notification. How Plasma-style notifications can be distinguished from DrKonqi?

Comment 4 Martin Klapetek 2016-01-13 17:14:08 UTC

Can you still reproduce this crash?

Comment 5 nikita.rogatnev 2016-01-19 07:53:54 UTC

Yes, KDE is now 5.17.0, but bug remains

Comment 6 Andrew Crouthamel 2018-09-19 14:43:06 UTC

This bug has had its resolution changed, but accidentally has been left in NEEDSINFO status. I am thus closing this bug and setting the status as RESOLVED to reflect the resolution change.
