That's what I'm most alarmed about. How did that junk appear?

Are those things in the SVG files? If they are, it's like Microsoft Word 
keeping old revisions when you publish a .doc.

Qt Software dept., part of the Devices Organisation (for short, "D-Qt"). At 
least until the next corporate reorganisation. TT/N is also valid, a short for 
"Trolltech, a Nokia Company".

I have found someone in the office who seemed interested in fixing issues. He 
has, however, no more clue than I do about the filters and blurs. So we cannot 
promise anything for the time being, other than fixing the blatant problems.
