http://commons.wikimedia.org/wiki/File:Noncommutative_Example_Concatenation.svg has an SVG file that gets rendered incorrectly. Normally the text should read:

EA+T≠T+EA
(EAT)≠(TEA)

For reasons yet unknown, the renderings mediawiki displays read thus instead:

EA+≠+TTEA
()≠()EATTEA

The cause of this problem is a bug in librsvg:
https://bugzilla.gnome.org/show_bug.cgi?id=624158

I don't know if you want to wait till librsvg comes up with a fix, or if you have the resources to contribute towards a fix or implement a patch locally. I've suggested a patch upstream, but don't know if this is the correct approach.
