Comment 4 for bug 409540

komputes, this issue is unreproducible in LibreOffice Draw via the Terminal:

cd ~/Desktop && wget https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/409540/+attachment/651852/+files/fw9_ev.pdf && unoconv --listener && unoconv -f odg fw9_ev.pdf && lodraw -nologo fw9_ev.odg

text looks good. Does this work for you? Could you please be more specific about what is "mangled"?
