Ah, OK, on the test page.
Well, this bug looks to me very much like bug #321932.
But I'd rather not have you try everything that was tested there (at least not until Till ask you).
So let's try to collect infos that Till have asked there.
Please give the results here of: dpkg -l ghostscript defoma gsfonts ttf-mscorefonts-installer
Also the output of: gs -c 'loadallfonts quit'
