            Bug ID: 465987
           Summary: Power Module (power devil or whatever) won't start at
                    all with latest plasma.
    Classification: Plasma
           Product: Powerdevil
           Version: 5.27.0
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: plasma-b...@kde.org
          Reporter: brendan.ran...@gmail.com
                CC: m...@ratijas.tk
  Target Milestone: ---

Application: org_kde_powerdevil (5.27.0)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.11-200.fc37.x86_64 x86_64
Windowing System: X11
Distribution: Fedora Linux 37 (Workstation Edition)
DrKonqi: 5.27.0 [KCrashBackend]

-- 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!

Brendan

The crash can be reproduced every time.

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