SpliX printer driver: intrepid->jaunty upgrade does not upgrade the PPDs of the existing print queues

Binary package hint: cups

I just upgraded intrepid to current jaunty (amd64) on one of my boxes with a Samsung ML-1610 laser. After that, the printer cannot print anything any more:

$ echo -e 'hallo\nwelt' | lp
lp: Das Format „text/plain“ wird nicht unterstützt!
$ lp hello.pdf
lp: Das Format „application/pdf“ wird nicht unterstützt!

(meaning "format .... is not supported"). This is reflected in the error_log:

D [31/Mar/2009:17:34:29 +0200] [Job ???] Auto-typing file...
I [31/Mar/2009:17:34:29 +0200] [Job ???] Request file type is application/pdf.
D [31/Mar/2009:17:34:29 +0200] Print-Job client-error-document-format-not-supported: Das Format „application/pdf“ wird nicht unterstützt!

If I delete and recreate the printer, it works. printers.conf has no noticeable difference, but the generated PPD files differ:
