kprinter: error after upgrade

[Philipp Pagel <pDOTpagel@gsf.de>]

       Hi!

I am running Debian testing and after a recent update some part of kde
printing broke. I have a nicely working CUPS with several printers
installed. All of them work fine if I do

lpr -P SOMEPRINTER somefile.ps

or

lpr -P OTHERPRINTER otherfile.pdf

But if I try to print via kprinter a dialog Box pops up saying

"Error while printing file"

followed by

(Catastropy! - KNotify)
"A print error occurred. Error message received from system:

Error while reading filter description for true. Empty command line
received."

And the follwoing error message goes to STDERR:
"QFile::open: No file name specified"

For some printers I was able to fix the problem by simply deleting and
re-installing them. Others refuse to work even after that. For the ones
that still don't work the test page (during installation) printed fine
but the above error remains.

Any hints? Any debug options I could use to get more information on the
nature of the problem? Any good URLs describing the filter workflow and
its config files?

Thanks

        Philipp
