-- Information about the crash:
The relevant stack trace/dump is attached. I haven't done anything different or special compared to what I used to do in the previous revision. The only "unique" thing that I'm doing is logging in remotely via x2go to a "x" plasma session.

Thx much!


The crash can be reproduced every time.

-- Backtrace:
Application: KDE Power Management System (org_kde_powerdevil), signal: Aborted

Thank you for the bug report! Unfortunately the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

> #8  0x00007fafe96c3d37 in  () at /lib64/libKF5ScreenDpms.so.8

Could you please install debug symbols for kscreen, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks again!
