I had the same problem.

from shell:

kdecore (KAction): WARNING: KAction::initPrivate(): trying to assign a shortcut (Delete) to an unnamed action.
kdecore (KAction): WARNING: KAction::insertKAccel( kaccel = 0x828f7d0 ): KAccel object already contains an action name "file_quit"
kdecore (KAction): WARNING: KAction::insertKAccel( kaccel = 0x828f7d0 ): KAccel object already contains an action name "close"
kdecore (KAction): WARNING: KAction::insertKAccel( kaccel = 0x828f7d0 ): KAccel object already contains an action name "close"
kdecore (KAction): WARNING: KAction::insertKAccel( kaccel = 0x828f7d0 ): KAccel object already contains an action name "file_quit"

when open labels editor, and barcode generator doesn't work without shell's errors....

solutions?
