Version of package kded5: 5.12.0-0ubuntu1~ubuntu15.04~ppa1 I "solved" the problem on my own by removing *all* configuration and caching data from my home directory, including but not limited to: .cache .config .dbus .gconf .gnome2 .gnome2_private .kde .local So, afterwards, I got back a working kded and with it a working plasma. However, of course, I lost all my personal settings. Thank you for reporting this bug in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the issue with a recent software version? If you can reproduce the issue, please change the status to "REPORTED" when replying. Thank you! Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please mark the bug as REPORTED so that the KDE team knows that the bug is ready to be confirmed.

Since a reboot I found that custom global keyboard short cuts where not working at all (e.g. using <WIN> + <F1-4> to switch between the four Activities I regularly use. I then wanted to check the system-settings only to find out in the "Background Services", that an error-box popped up saying "Unable to contact KDED." My workstation usually runs 24/7 and I only reboot when really necessary. So during the last run there where several updates, which was from 2015-08-08 18:11 - 2015-08-23 13:01 UTC. I then tried to start kded5 manually, which gave me a segmentation fault: $ kded5 [2015-08-25T07:20:58.749 CEST] warning - 0x25bcda0 - kded5(11877)/(default) unknown: Qt: Session management error: networkIdsList argument is NULL [2015-08-25T07:20:59.878 CEST] debug - 0x25bcda0 - kded5(11877)/(kf5.kservice.sycoca) unknown: Trying to open ksycoca from "/home/ancoron/.cache/ksycoca5" [2015-08-25T07:20:59.879 CEST] debug - 0x25bcda0 - kded5(11877)/(kf5.kded) unknown: kded module "printmanager" still uses .desktop files ("kded/printmanager.desktop").
