            Bug ID: 338868
           Summary: Old system tray icons, failing clipboard management,
                    DrKonqi authentication, WiFi login, ACPI handling
                    after returning from standby
           Product: kde
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: devurandom at gmx.net

As I cannot send DrKonqi reports directly when in this stage ("Error sending
the  crash report: /Received unexpected error code 410 from bugzilla. Error
message was: You must login before using this part of KDE Bugtracking
System../"), I post the contents of the kcrash report below. The report does
not contain the KDE product and component, which DrKonqi identified, and I
could neiher find a "kded" product, so I used kde/general instead.

Application: kded4 (4.13.3)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-35-generic x86_64
Distribution: Ubuntu 14.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I returned the computer from standby and plugged in the power chord.

- Unusual behavior I noticed:
* The icons in the system tray partly (not all of them) change from the current
Oxygen style grey icons to the old colourful icons from the beginnings of the
KDE 4 era.
* I cannot manage the clipboard anymore – Klipper does not react to my attempts
to select one of the multiple clipboards, and copy and paste is broken.
* I am unable to login to WiFi networks.
* Pressing the computer's power button will shutdown the system immediately,
instead of showing the KDE logout/shutdown/reboot dialog.

Restarting the computer resolves this issue until the next time I wake the
computer from standby. The problem does not appear on every wakeup, though.

This is the first time, that DrKonqi displays for this issue – before KDE would
only silently stop working in the manner described above. Since I suspected an
undetected kded crash already, I take this crash report as an evidence of this
hypothesis.

My guess is that this has something to do with failing interprocess
communications, maybe because DBus is not reachable by the restarted kded?

The crash can be reproduced sometimes.

-- Backtrace:
