Strange. > BTW, the crashing stops if I disable Akonadi Nepomuk Feeder, so I guess it's > somewhat Akonadi related. Or at least the data Akonadi stores in Nepomuk. I see.

No crashes, nothing in syslog. Seems to be triggered by something accessing virtusos then. Hard to debug :( Maybe if you run nepomukserver in a terminal/shell, probably running akonadictl start in a second? Maybe one of the processes involved logs something of interest to stdout/stderr. Other than that I've run out of ideas. Don't know much about the Nepomuk/Virtuoso part. Cheers, Kevin -- Kevin Krammer, KDE developer, xdg-utils developer KDE user support, developer mentoring
