Description Alex Merry 2010-09-29 13:02:51 UTC 
Application: kded4 ($Id: kded.cpp 1151015 2010-07-17 13:50:01Z pokrzywka $)
KDE Platform Version: 4.5.69 (4.6 >= 20100920) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I've just built and installed wacomtablet from kdereview, and I started the Wacom Tablet service from the Service Manager KCM.  This caused kded to crash.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault

Jörg, could you request your own product/component entry in bugs.kde.org so? Ideally systemsettings/kcm_wacomtablet, and a new wacomtablet product.

Comment 9 Pascal d'Hermilly 2010-12-28 22:35:01 UTC 
I'm experiencing a similar chrash with KDE 4.6 RC1 ... Has the crash not been fixed? Or is it the version (1.2.0-1) which is old?

Comment 10 Roey Katz 2011-01-13 13:40:05 UTC 
I'm getting the same results since 4.6b1 now.  And I'm currently on 4.6rc2.   None of my keyboard settings are respected, and I've filed a bug for it here:  
https://bugs.kde.org/show_bug.cgi?id=259387 and I think the bug I filed is a duplicate of this.

Now I realize that it is because kded4 crashes on startup since 4.6b1.

Here is the output from kded4's crash dump:

Comment 18 Christoph Feck 2011-04-24 17:23:51 UTC 
The fix is not in KDE SC 4.6.2, but in the kcm-wacomtablet module. Please update it, or ask you distribution to provide a current version.
Comment 19 Ancoron 2011-04-24 19:13:16 UTC 
OK, thanx for this info, will try that.
