Export as svg - font problem?

Hello,

I am trying to create a vector image off a musescore file. I exported as svg and my system doesn't seem to recognize the note heads. I assume this may have something to do with a missing font (among other reason from what I read in these forums). I tried exporting as PDF (that worked fine) and then opening with Inkscape and got the same problem.

I thought I may try to install a font mscore-20, would that be the right thing to do? Still I can't find it anywhere. Could anybody tell me what I should do?

Thanks heaps,
Fede
