OP, how did you solve this problem? I am running Slackware 14.1 with KDE 4.13.3 and I am with the same problem.
I tried a few things I've found:
Tweaking:
Code:
# echo 10240 > /proc/sys/fs/inotify/max_user_watches
It didn't work, the limit was raised but it didn't solve the problem. Now the limit went back to the normal value (8192).
Removing local nepomuk entries:
Code:
$ rm -rf ~/.kde/share/apps/nepomuk/
It seems
this is the solution but Slackware doesn't have /etc/systcl.d. Where are those files located?
