Images of formulas look shoddy when opened with gimp

TracMathplugin (here 0.3) generates the formulas as tiny .png images embedded into the html page. These images look decent when viewed with browsers such as firefox (here 3.6.17). However, if one downloads the image and opens it up in image manipulator such as gimp, the image looks very grainy/pixelated. Only truely black pixel are visible, everything gray is lost (made transparent).
The problem can be remedied within gimp if the color palette (in the gimp menu, that's Image/Mode) is changed from indexed to rgb. Then suddenly gray pixels become visible.
I don't know how the pngs are rendered, so I am not much of a help here but hopefully the palette thing gives a clue to this.
