Application: akonadi_nepomuk_feeder (4.9) KDE Platform Version: 4.9.97 (Compiled from sources) Qt Version: 4.8.4 Operating System: Linux 3.5.6-1-ARCH x86_64 Distribution (Platform): Archlinux Packages -- Information about the crash: - What I was doing when the application crashed: I cleared out all the Akonadi configuration (~/.local/share/akonadi and ~/.config/akonadi) and started Akonadi (akonadictl start or the configuration module). Then the nepomuk feeder crashed. It crashes several times, until akonadi decides it has crashed too much and refuses to start it again. I'm using the default settings (MySQL backend, internal). This also happens with a fresh test user, but only if I manually restart akonadi after logging in (the crash doesn't happen when I log in).

Alex, perhaps https://git.reviewboard.kde.org/r/108378/ fixes this?
Yep, that seems to fix it.

Git commit 114d49a7a09e5b31dfc65ab0c277a59dbd233c52 by Dan Vrátil. Committed on 13/01/2013 at 23:07. Pushed by dvratil into branch 'KDE/4.10'. Fix NepomukFeeder crash when Akonadi is empty When there are no items in Akonadi, there are no collections to fetch. However Akonadi::CollectionFetchJob() asserts when constructed with an empty collection list. This regression was introduced in commit 1b2444.
