kdialog error message

[Jerry]

FreeBSD 8.3-STABLE
kde Platform Version 4.8.4 (4.8.4)

I am attempting to create a custom action in "claws-mail". The action
command line reads:

	| kdialog --msgbox "Characters: $(wc -c)"

This works fine except it also issues an error message:

--- Ended:  kdialog --msgbox "Characters: $(wc -c)"
kdialog(26489)/KSharedDataCache: Unable to find an appropriate lock to guard the shared cache.  This *should* be essentially impossible. :( 

kdialog(26489)/KSharedDataCache: Unable to perform initial setup, this system probably does not really support process-shared pthreads or semaphores, even though it claims otherwise. 

kdialog(26489)/KSharedDataCache: Unable to unmap shared memory segment 0x8095c3000 


Since this works on other OSs, it appears to be a problem with FreeBSD.
Can anyone elaborate on it?
