            Bug ID: 366335
           Summary: Crash of KDE daemon following vnc login
           Product: kdelibs
           Version: unspecified
          Platform: Debian stable
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: kded
          Assignee: unassigned-bugs at kde.org
          Reporter: fournierjc at upmc.edu

Application: kded4 (4.14.2)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 8.5 (jessie)

-- Information about the crash:
- What I was doing when the application crashed:
Running Debian Jessie (Linux 3.16.0-4-amd64)
Running KDE SC Version 4.14.2
Iniate vnc session (using vnc4server)
see the crash screen as soon as connect through vnc (running VNC viewer on
Windows 7)

- Unusual behavior I noticed:
KDE Daemon closes unexpectedly. 
- I recognize that this is similar to bug 344395 - but KDE 5 is not available
for the latest stable version of Debian (which I'm using). Is there no
workaround for this? 

- Custom settings of the application:
All settings are the defaults. This crash happens 100% of the time

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
