New Cairo PDF Export mangles font kerning (OS X)
I have an old map project that I've updated for the new year with Inkscape .46 - I then send it off to the printers as a PDF. However this time the old method for PDF export has been removed and replaced by cairo. It works, but the font kerning is all wrong - the letters seem to be spaced too far apart.
This is much worse for small font sizes than for large font sizes - could it be an issue of precision?
Here are some pictures of a magnified part of my document.

I never had this problem with .45's PDF export - can I replicate this behavior in the new version?

It looks as if the kerning is magnified (almost doubled). Letter pairs that need to be closer are too close, letter pairs that need to be wider are too wide.
It could be an issue with relative vs. absolute kerning information, e.g., that the relative info is taken to be absolute or vice versa.

Sounds like the pango kerning bug with non identity scaling

It's not just font kerning. Here's a quote from my post of several days ago:
I grabbed an SVG file from Wikipedia that showed the infamous CIE 1931 chromaticity horseshoe to modify for an article I was writing. When opened in Inkscape, instead of the horseshoe there was a rectangular pixmap with the outlines of the horseshoe embedded in it.
Time for Mr Clipping Path to come to the rescue.
Except there were some weird results when trying to use the diagram, now with the horseshoe clipped out of the background pixmap so that it appeared as it does in the Wikipedia article:
* ... When exported to PDF via Cairo, the clipping path had gone AWOL so that the PDF appeared as the SVG when I first opened it, a full rectangular pixmap.
Has anybody had a similar experience?
Regards, Hedley
