Description Tom Max 2009-09-03 20:57:33 UTC
Version:           4.3.1 (using Devel)
OS:                Linux
Installed from:    Compiled sources

every time kde4.3.1 starts, the crash handler window appears because kde4-window-decorator crashed.

the backtrace shown an assert, but it is not full and I can't found the debug symbol for libkdecorator :(

here what gdb tells:

kde-window-decorator is developed by Compiz. Please report to them

please note that my bug is triggered by an assert,
bug 143419 is triggered by a destruction...
in my opininion these fault are very different,
also because 143419 was detected on KDE 3.5.6

Comment 3 Thomas Lübking 2009-09-03 22:00:11 UTC
from a kwin/kde pov the bugs are equal in "it's someone elses problem"
(it crashes in compiz/kwd and with the iaora deco - which is not shipped with KDE)
detailed distinction will be done by the KWD devs

as the unstable api is in use this /might/ be due to a version mismatch (you updated KDE but not compiz -or kwd has not been aligned to changes in KDecorationUnstable at all- and thus the asserted dynamic cast fails.)
Comment 4 lucas 2009-09-04 04:07:09 UTC
Compiz bug.
