Starting Pd like this "$ LANG=C pd" didn't solve the error, the plugin~-help file was still white. But changing these settings did solve the problem:
in ubuntu studio/Settings manager > Language support > Regional Formats : display numbers, dates and currency in the usual format for: English (UK)

and next restart the computer. My previous setting for displaying 
numbers was "Deutsch"
I'm glad that the problem is solved, thanks for the suggestion!
