TDE Printer error message in kmail or ps/pdf viewer

Since upgrade from tde 3.5.13 (ubuntu 12.04) to 14.0.4 (ubuntu 16.04) I get the attached error message when printing from kmail or from the ps/pdf viewer. It looks like a misinterpreted linefeed after the mime type.: application/postscript\012- \012-application/octed-stream somewhere in the config files or in the tde printer driver. Ignoring the error prints the file, but preview is not possible. The print system is cups. Is this an known error? Thanks in advance Stef
