As an option, you can download the fonts from the Wolfram site and then almost follow the instructions to make the package removable:
mkdir /usr/share/fonts/truetype/ttf-mathml cd /usr/share/fonts/truetype/ttf-mathml unzip path/to/MathFonts_TrueType_41.exe defoma-font register-all /etc/defoma/hints/ttf-mathematica4.1.hints
Only now you no longer need to uninstall the broken package, as you got the fonts where they are needed.
