iconvert -size 400x400 s3.svg s3.png looks like this, but it should be a rotated square touching the circle at 4 points



s3.svg:

	<g transform="rotate(48 200 200)">

We can reproduce the problem you posted. Currently we do not have an ETA on a fix. If you want to take a look yourself, see coders/svg.c, method SVGStartElement(). Inside this method is a case for "rotate". It looks like the tx and ty members of the affine structure is not set properly.
