Description Michal Slonina 2009-10-29 11:24:14 UTC 
Application that crashed: kompare
Version of the application: 4.0.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.6.0
Operating System: Linux 2.6.30.1 i686

What I was doing when the application crashed:
kompare works fine when launched standalone,
but it crashes when launched from kdesvn

The kdesvn version is:
Qt: 4.6.0
KDE: 4.3.2 (KDE 4.3.2)
kdesvn: 1.4.0

Uhm, yes, the backtrace matches. We never figured out what caused that bug and what "fixed" it. :-(

The line which fails is the query for Kompare/ViewPart. Somehow your services are not registered properly. Try running "kbuildsycoca4".
Comment 2 Michal Slonina 2009-10-29 13:33:44 UTC 
Hi Kevin,

BIG Thanks for your quick reply.

Indeed running kbuildsyscocoa4 solved the problem,
so the bug is probably distro related (i'm using gentoo ebuilds).

Maybe I could write a patch that checks for that condition and instructs
the user to run kbuildsyscocoa4 ? Or just force the kbuildsyscocoa4 run ?
  What do you think ? 


Regards, Michał Słonina.
Comment 3 Dario Andres 2009-10-29 14:16:44 UTC 
AFAIK, kbuildsycoca4 should be run after building/installing, so KDE will properly update its service/desktop-files cache and recognize the new installed plugins...
Comment 4 Kevin Kofler 2009-10-29 17:47:21 UTC 
Normally, kbuildsycoca4 should be run automatically when kded detects a change in a service file. For some reason, that doesn't always work. But that's a kdelibs issue, not a Kompare one, and there's probably some bug report about that already.
