On my wiki (MW 1.5.5),
<math>x_{1,2}=\frac{-b\pm\sqrt{b^2-4ac}}{2a}</math>
is rendered like this:

while it should be rendered like this:
http://en.wikipedia.org/math/0/f/1/0f16872ccd04ca7ecce3544bc3521ff1.png
Any idea where I should look to fix this? It's a Debian Stable installation, with the whole texvc toolchain set up.
Thanks,
Erik
