regarding the font issues in general: did you ever try to use Pango for
the fonts instead of Cairo?
In my app I'm using a PangoContext to place text into the page, but
this also causes problems, at least on Windows.

I have the same problem, it is also black when the document is printed
to a PDF printer on Windows (e.g. PDFCreator from
http://www.pdfforge.org/).
The attached little example code demonstrates the problem. Probably I'm
doing something wrong, if so, can anyone tell me what?
The code works fine on Linux, on Windows with GTK 2.12.1, Pango 1.18.3
and Cairo 1.4.10 the created rectangle is completely filled with black.
Is this a GTK/Pango problem, in Cairo or in my code?
See http://www.uvena.de/tmp/cairo/print_linux.pdf and
http://www.uvena.de/tmp/cairo/print_win.pdf to see what it looks like.

I can't reproduce this, on my Windows 2000 box I can overwrite existing
files as expected.
