Cups filter failed for jpg and libreoffice files, not for pdf

When printing e.g. jpg or libreoffice files I get a filter failed from cups, but not with pdf or the yast test page. I activateted debug-logging, but the cups error log does not show any error (openSUSE Paste; sorry for the long 600+ lines log).

I’m using the newest version of tumbleweed and a Kyocera ecosys P5021cdw printer with ECOSYS P5026cdw.kpdl.

Has anyone an idea how I can get a reasonable error message to start solving the problem? Or give me a hint deriving from the log to solve the problem?
