Hi!

Since I've played a little around with Nepomuk and Strigi any right mouse click crashes my Konquerer (SVN Trunk Version from today). Also the backtrace looks in my eyes like it's a problem with some left overs of the Nepomuk/Strigi experiments. I turned the desktop search to off in the the system settings.

Does anybody know what could cause these crashes and how to solve the problem? How do I reset Konqueror/Nepomuk/Strigi to a clean state without deleting my whole $KDEHOME folder?

My svn version is about 12 hours old, and I am unable to reproduce the problem. Given the severity of the problem, it has likely been fixed. You could try updating again, and failing that try with a clean ( new ) user. If you are still able to reproduce after this, I would recommend asking on the kfm-devel@kde.org mailing list.

Thanks for your answer, I have that problem since several days, and I also would expect that such a big problem would be already fixed, or caused at least some more attention. So I think it's a local problem with some config files on my hard disk.

At least I would like to try to reset konqueror/strigi/nepomuk to default config file and delete left over files from my experiments with these services, before I'd ask for more detailed help. But I'd really would like to avoid deleting the complete $KDEHOME as it holds also my kmail configuration with a lot of filter rules, and other config files.

Trying with a different user is a bit problematic since this is a $HOME based kdesvn-build installation, so I'd have to change a lot of permission and paths to run that as another user.

[Edit] I found my old beloved kdesu in ~/kde/lib/kde4/libexec/ (any reason why this is not in $PATH anymore?) and could actually launch konqueror as a different user, but the crash remains.

The configuration files in question are called konq* ( there are quite a few ) and nepomuk* ( three of these )
they are all located in $KDEHOME/share/config

Thanks for the help, deleting all konq* and nepo* files in $KDEHOME/share/config and restarting KDE didn't help, konqueror still crashes.

I still do not believe that this a real bug.

The backtrace looks like this, maybe you see a hint in that what's wrong ...

I know that this won`t help, but I`m unable to reproduce.
do you have the most recent builds of kdesupport too?

Yes, except for some things in playground kdesvn-build finished without any problems, but I'll try a sync right now just to be sure.

I'll report back when it's done.

[Edit] Now I run into some problems with this commit from yesterday. kdelibs fails to install because of a missing kdelibs/cmake/modules/FindKdepim.cmake. I'll try again later and if that doesn't work start with a clean build directory over night.

Try removing the Nepomuk databases as well as they could be corrupted ( $KDEHOME/share/apps/nepomuk )

Thanks for the hint ... but no avail.

But, finally I got the right button context menu back. I deleted the whole installation and rebuild everything from scratch and disabled the building of everything from playground.

I still don't know what caused the crash, but it's now fixed.

Thanks for all you help!

Also when marked as "solved" let me explain what happens (may also help someone else not to rebuild everything).

There where some changes in the Nepomuk libs in trunk. With them applications using Nepomuk need to call some init method before using Nepomuk. Before that, that was optional.

Konqueror itself does not use Nepomuk yet, but a Konqueror plugin in Nepomuk playground does. That was not adapted to the change in the Libs and so caused the crash.

So only users with Nepomuk Playground things installed were affected. But it is fixed there. So if you still suffer from this: Update the all of playground/base/nepomuk or only playground/base/nepomuk/konqueror to current trunk.
