Description René Serral 2011-11-22 14:54:11 UTC

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.3 (4.7.3) (Compiled from sources)
Qt Version: 4.7.3
Operating System: Linux 3.1.0 i686
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
I just logged in and nepomuk started crashing, everytime I restart it it crashes again.

I also noticed that virtuoso crashes also, in my dmesg I have:
[26142.998907] virtuoso-t[20125]: segfault at ffffffff ip 0846818c sp b5e70980 error 6 in virtuoso-t[8048000+985000]

Any hints?

The crash can be reproduced some of the time.

-- Backtrace:

Comment 1 Sebastian Trueg 2011-11-23 10:12:31 UTC

Should be a duplicate of bug 286690. The backtrace is different but the problem the same. If it does in fact not fix the problem I need to take further measures (which are already in my head).

Comment 2 Sebastian 2011-12-15 18:55:44 UTC

Created attachment 66784 [details]
New crash information added by DrKonqi

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

- What I was doing when the application crashed:

After upgrading to 4.7.4 Nepomuk just keeps crashing at login. It happens every time. Problem is the same as with the original poster.
I just logged in and nepomuk started crashing, everytime I restart it it crashes again.

Again, this is 4.7.4 and it did not happen with 4.7.3
