Hi again,
Do something with .kde4/share/apps/nepomuk . Either move it or
delete
it. I had the same problem after 4.5 update and just removed it and let
KDE recreate it.
Unfourtunatly this didn't help, the same error messages about akonadi
as well as nepomuk still appear at startup.
KDE-4.5 turned out to be a horrible experience until now :/
Thanks, Clemens
PS: Any idea when updated libdbus packages will hit fedora? I still
have those dbus-related freezes.
