I know rsvg has its bugs, but I never seen this one and I don't think it's due to rsvg.

The image, if rendered at normal size is rendered perfectly: http://upload.wikimedia.org/wikipedia/commons/thumb/5/59/Planetary_transit_sr.svg/800px-Planetary_transit_sr.svg.png - actually the arrows are not rendered but this is a known rsvg bug.

However, if rendered at a reduced size, the text gets strange spaces at random places: http://upload.wikimedia.org/wikipedia/commons/thumb/5/59/Planetary_transit_sr.svg/300px-Planetary_transit_sr.svg.png - for example the text at bottom right that reads "Светлосна крива" becomes something like "Св ет  лосн а кри".

I don't think this is a rsvg bug b/c on my computer rsvg (2.18.2) renders the image in reduced size just fine, and I don't see how it could be a MediaWiki bug. My guess is that this is caused by bad fonts installed on the servers.
