It does crash at every login, but it just segfaults, so no debug information
Comment 2 Christophe Marin 2011-09-02 21:51:59 UTC

New crash information added by DrKonqi

nepomukservicestub (0.2) on KDE Platform 4.7.1 (4.7.1) using Qt 4.7.3

- What I was doing when the application crashed: After the full upgrade to 4.7.1 and open the session I get this backtrace, which was never complete on 4.7.0 

At the same time a second backtrace is launched but only with that 
Application: Nepomuk Service Stub (nepomukservicestub), signal: Segmentation fault

(in fact is nepomukstub storage) that crash at each login. One or two times

-- Backtrace (Reduced):

New crash information added by DrKonqi

nepomukservicestub (0.2) on KDE Platform 4.7.1 (4.7.1) using Qt 4.7.4

- What I was doing when the application crashed:
Each time I login, it crashes. This is a clean Arch install (installed it yesterday afternoon)
- Custom settings of the application:
None, everything is default

-- Backtrace (Reduced):

Comment 5 S Clark 2011-09-08 19:54:51 UTC 
I can't tell for sure if my "nepomukservicestub segfault" problem is the same one, but I've been getting it since 4.7.0, still getting it in 4.7.1 (Arch Linux).
I managed to finally get the relevant packages recompiled with debug information, so I now have a backtrace that is supposedly useful.

For me, I get the segfault shortly after starting KDE.  If I "restart", it happens again a few seconds later.  Here's the backtrace:

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

Comment 6 Sebastian Trueg 2011-09-19 12:53:40 UTC 
Does this still happen?
Comment 7 Christophe Marin 2011-09-19 13:05:51 UTC 
my coredumps directory says so (with kde-runtime from two days ago)

Git commit 4a81ffec713b7d9f21e3c0aac702f2e80fc62616 by Sebastian Trueg.
Committed on 19/09/2011 at 16:11.
Pushed by trueg into branch 'master'.

Use a direct connection for the job's result signal.

Otherwise the KJob autodelete feature kicks in, deletes the job and
makes the slot crash.
