Comment 1 Sebastian Trueg 2010-07-27 11:17:58 UTC 
Is this still happening with latest Soprano (2.4.64) and kde trunk?
Comment 2 Cyrille Dunant 2010-07-28 01:16:12 UTC 
I would gladly test, but suse packages only 2.4.64. Are there many changes ?
Comment 3 Sebastian Trueg 2010-07-28 16:40:49 UTC 
Soprano 2.4.64 is the latest actually. If the crash still happens with that then I need to further investigate.
Comment 4 Sebastian Trueg 2010-07-29 11:37:28 UTC 
Also it would be good to know if the crash does still happen with the latest unstable libdbus >=1.3.1
Comment 5 Nicolas L. 2010-08-14 19:37:33 UTC 
Please try latest libdbus and tell here if this is still valid
Comment 6 Cyrille Dunant 2010-08-14 19:48:19 UTC 
I have tried the latest dbus, and did not have this bug anymore. However, changing dbus caused other (unrelated) problems and I reverted.

But the problem did not reappear, so I guess it was unrelated, but rather due to some other component which got updated.

[Comment from a bug triager]
Additional note: bug 251418 and bug 252140 have similar backtraces with an trunk KDE (4.5.68/69) and Soprano 2.5.62/63

[Comment from a bug triager]
Reopening because there are more cases, and NEEDSINFO/FIXED was an invalid state.

SVN commit 1215091 by trueg:

Properly handle DBus error replies when checking the init state of services.
This fixes a bug where services are started before the deps are initialized
and all sorts of problems appear.

Hi !
Im using Fedora 16 and KDE 4.7.4 !
And frequently when i shutdown in kde (CTRL + ALT + DEL)
How i had configured inittab to multiuser mode, when the X closes, it shows a lot of logs ... and aftter logs and inform that nepomuk crashes and stop the shutdown operation, it shows the command line and i had to execute porweroff, to realy poweroff the machine !
It will be fixed ? Or how to fix this ?
Bye
