I've converted a series of EPS graphics to SVG using Inkscape. Most of these graphics have a "transform" attribute that is used to reduce the dimensions/stroke-width of each path. On open, Illustrator handles the dimensions correctly, but does not appear to apply the stroke-width correctly. I've written a PHP script that removes the transform by manually overriding each coordinate/stroke and the SVG's seem to now work correctly. Here's the link to the library if anyone wants to try it:

There's also a more in-depth description of this bug.
