[cairo] crash report and question

[bulia byak]

1. I realize it's a lot of hassle to reproduce this crash as I did,
but since it's obviously caused by a font, hopefully you can reproduce
it in a simpler way. I get it when doing --export-ps from command line
using Inkscape SVN trunk, only on Windows. Please let me know where I
can upload or send the bad font and the SVG file using it. Here is the
backtrace, cairo version is 1.8.0:

2. How can I set the bounding box of an EPS file produced by cairo?
Once I set the eps flag on PS surface, it seems to ignore the width
and height I set on the surface, and sets the bounding box to the
minimum extent of the mark on the page. Which is useful in some cases,
but in my case I want to explicitly have my own "0 0 width height"
bbox. What's the trick?
