Since upgrade to plasma-5.5.1, same for 5.5.2, this same crash is now happening all the time after unlocking from screen standby. It is happening on a ThinkPad with dockingstation, lid closed, and a Displayport-connected external screen. Created attachment 96291 [details]

...and here's my backtrace. Reproducible each time by just switching off and on the external DP screen while kscreenlocker is active. Can't reproduce it with LVDS only (no external screen attached).

Stacktrace with ScreenLocker entry
I have this problem as well -- I use nightly build PPAs; this happens with almost exactly the same setup
External monitor (I typically set my desktop to only display on the external display) over displayport.
Trivially reproducable (on a Dell laptop) by locking the screen whilst using the external display, and turning off the external monitor (which is the primary desktop).
Attaching a stacktrace as well.
This is on qt 5.5.1, and kde 5.17 (built on the 27th of dec, from the ubuntu unstable ci ppa) Created attachment 98443 [details]
stack trace segmentation fault
Currently I cannot keep plasma working for more than one day.
My suspicion is that the Monitor/Display gets powered down after a work day being unused.
Then when I turn the monitor on again something is different from just turning the monitor off and on again (which ksmserver survives).
Gentoo, kde-plasma/plasma-meta-5.5.5
Same here. ksmserver crash on Gentoo amd64 with Qt 5.5.1 and Plasma 5.6.2. Is this the same bug as the other crashes when plugging/unplugging monitors that was supposedly fixed in Qt 5.5.x or a KDE issue? Dear Bug Submitter, This bug has been stagnant for a long time.
