4.4.0. Bug still here :) Just update, switch on nepomuk, start dolppin and in a minute it crashed. :(
Comment 2 Sebastian Trueg 2010-02-11 11:02:49 UTC 
Probably also related to http://bugreports.qt.nokia.com/browse/QTBUG-7475
Comment 3 Vovochka 2010-03-03 06:36:55 UTC 
4.4.1 with qt 4.6.2

Looks like ok :)
Comment 4 Vovochka 2010-03-05 01:29:36 UTC 
Nope. Bug is still here.
But i have some thoughts.

After i upgrade 4.4.0 -> 4.4.1 and re login to the system i started a nepomuk service. Strigi begins to check/index my files, in memory appears one more database eating almost 100mb... Dolphin starts to show additional info for files, search starts to work and everything was cool. Life was good. :)

But then i was have to re login again. At startup, when kontact with akonadi where starting, an akonadi progress par freezes for almost 20 sec and then apears a kontact with akonadi error messages. One of them, was telling that nepomuk search service doesn't registered at d-bus. I went to system settings -> desktop search. Nepomuk checkbox was on, but not the strigi's one. I switched it on, press apply button and error message appears: "Failed to start strigi. May be needed programs not installed.". Unckeck all, apply, check all, apply and systems settings dialog hangs for about 30 sec. Just like akonadi at start up. Bye some such manipulations i was able to get strgig/nepomuk icon at systray, and it was looks like it is indexing something, but no virtuoso in memory, no cool additional info and no search in dolphin, akonadi doesn't see nepomuk search service at d-bus. Nothing.

Looks like, when i was logging off something wrong happened and nepomuk is not able to start normally anymore.

P.S.
Some time near strigi checkbox i have such message:
The name org.kde.nepomuk.service.nepomukstrigiservice was not provided by any .service files.

P.P.S.
When nepomuk is acting like this, dolphin crashes like it was described at first message in this report :)
Comment 5 Sebastian Trueg 2010-03-05 10:53:46 UTC 
could you please run "nepomukserver" from a shell and have a look at the output.
Comment 6 Vovochka 2010-03-09 05:40:43 UTC 
The problem was in deferent versions of virtuoso server and database.

I delete old database and everything is starting fine now.

But looks like today i'll write one more report on nepomuk. :(

P.S.

When nepomuk faild to start strigi backend, it looks like doesn't registering search service at d-bus. In this case dolphin has such crasches.

New crash information added by DrKonqi

dolphin (1.5) on KDE Platform 4.5.3 (KDE 4.5.3) using Qt 4.7.1

- What I was doing when the application crashed:

Nothing. Just opened Dolphin.
Dolphin has crashed in few seconds.

Previously D-Bus 1.4.0 was installed manually (with system reboot).

So it doesn't matter whether D-Bus v.1.2.x or v.1.4, the bug is still observed.
