It works now again.

I have noticed a *lot* of files with the following scheme for their 
names, all in $HOME of the said user:

   .DCOPserver_myhostname_:NNN -> .DCOPserver_myhostname__NNN
   .DCOPserver_myhostname__NNN

(where the filename with the ":" was always a symlink pointing to the
one with the replacement "_", and where "NNN" was a figure ranging
from "0" to "255").

I'm not sure what caused the creation of all those files, but somehow
there seemed to be a limit of 2^8=256 to their number. 

I deleted them all but the ones with "0", logged out of KDE and back
in, and now kprinter works again.

Will be watching if anything does re-create those files. So far I've
only the "*_:0" and "*__0" files here.

Cheers,
Kurt
