            Bug ID: 349434
           Summary: KDE Init repeatedly crashing on Fedora 21.
           Product: kdelibs
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: kded
          Assignee: unassigned-bugs at kde.org
          Reporter: jenevaray at gmail.com

Application: kded4 (4.14.9)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 4.0.4-202.fc21.x86_64 x86_64
Distribution: "Fedora release 21 (Twenty One)"

-- Information about the crash:
- What I was doing when the application crashed:
Google Chrome open, doing nothing complicated (no WebGL etc).  (I mention this
because I sometimes see graphical artifacts when I'm not running other
softwares)
This time, I was running an old application compiled against QT4 in a QT5
environment, which may or may not be related.
I'm running KDE5 in the OpenGL 2.0 context, on Fedora 21 (repo at
https://copr.fedoraproject.org/coprs/dvratil/plasma-5/) .   Fedora Rawhide is
not an option for me, due to backwards compatibility issues (yes, the old
software is That Old).

- Unusual behavior I noticed:
Temporary graphical artifacts within both the panel and within the old
application's window, seemingly triggering redraws.  This proved to be
distracting, but not non-functional.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
