I just compiled koffice from trunk and all koffice applications (and only these) crash immediate after startup with quite similar tracebacks. This is the error i get in console after starting kspread:

bash-3.2$ kspread
kspread(16930)/kdeui (KAction) KActionCollection::setComponentData: this does not work on a KActionCollection containing actions!
================================ Creating ChartShapeFactory instance
KCrash: Application 'kspread' crashing...
sock_file=/home/tobias/.kde4/socket-akela-arch/kdeinit4__0

and here is the traceback: http://paste.ubuntuusers.de/391139/

for krita:
bash-3.2$ krita
================================ Creating ChartShapeFactory instance
krita(18887)/kdeui (KAction) KActionCollection::setComponentData: this does notwork on a KActionCollection containing actions!
KCrash: Application 'krita' crashing...
sock_file=/home/tobias/.kde4/socket-akela-arch/kdeinit4__0

traceback: http://paste.ubuntuusers.de/391140/

I'm using Arch64 and have the recent KDE from trunk but i'm using the qt packages of Arch.
