            Bug ID: 327798
           Summary: Programs crash with segmentation fault on close with
                    oxygen-transparen and qtwebkit
    Classification: Unclassified
           Product: konversation
           Version: 1.4
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konversation-devel at kde.org
          Reporter: 4k1r4.rulez at gmail.com

Application: konversation (1.4)
KDE Platform Version: 4.11.3
Qt Version: 4.8.5
Operating System: Linux 3.11.8-1-ck x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
  On program close (reproducible for konversation and amarok 100%) + on
log-out/shutdown programs crash with segmentation fault.
  The programs that crash on shutdown are kmix, nepomukfileindexer and
akonadi_nepomuk_feeder.

- Custom settings of the application:
  Using oxygen-transparent git version, revision 01ff651 . If using other
styles - nothing crash.
Also interesting part with konversation, it doesn't have qtwebkit as
dependency, If I remove qtwebkit from the system - konversation doesn't crash
anymore. neither do kmix, nepomukfileindexer and akonadi_nepomuk_feeder. 
Wasn't able to check for amarok since it cannot start without qtwebkit.

The crash can be reproduced every time.

-- Backtrace:
Application: Konversation (konversation), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
