Thank you for the report.

Are you able to attach a small example document that reproduces the problem?

Comment 2 Simon Matter 2013-08-07 12:04:34 UTC

Created attachment 783858 [details]
PDF with invisible text

If the file is run through ghostscript like this

gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=test-gs.pdf test.pdf

the output file doesn't include the invisible text anymore.
