           Summary: Kwin crashes when switching to KDE4 Window Decorator
                    with Compiz Fusion icon
           Product: kde
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: david.wooffindin at gmail.com


Application: kde4-window-decorator (0.0.1)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
I launch compiz with the compiz fusion tray icon (launched by "fusion-icon
--no-start").
Then I choose KDE4 window decorator instead of GTK decorator.

KWIN segfaults directly, systematically.
This has happened since all beta versions of kde 4.4 (can't remember if in
4.3... long time ago :) )

The crash can be reproduced every time.

 -- Backtrace:
Application: KDE Window Decorator (kde4-window-decorator), signal: Segmentation
fault
