Sentry Crash Report:

Description Rafis Kamaliev 2012-08-02 17:35:50 UTC

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.2 (4.7.2) "release 5" (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.1.10-1.16-desktop i686
Distribution: "openSUSE 12.1 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
run kmail
- Unusual behavior I noticed:
nepomuk index disabled
- Custom settings of the application:
akonadi is google enabled (i.e. imap, contacts), just downgraded from kde 4.8.4 because akonadi and kmail do not start with 4.8.4

-- Backtrace:
Application: Nepomuk Service Stub (nepomukservicestub), signal: Aborted

Git commit c4f3c8cee274c7429dcbcc84d3626ec767d06801 by Vishesh Handa.
Committed on 02/08/2012 at 23:00.
Pushed by vhanda into branch 'KDE/4.9'.

StorageService: Do not register the DBusInterface

We do not need the /org/soprano/Server dbus interface. No one uses it,
and we land up spawning an extra thread for this dbus interface (Soprano
code)

Additionally, they have been crashes when removing the dbus interface thread.
