Pascal,

I happened to have started looking into this yesterday; I can reproduce the issue. shared-mime-info is 
currently installed only on the stable branch and the only target that depends on it is devhelp-gtk3. 
Installing it and making sure that XDG_DATA_DIRS includes $PREFIX/share didn't prevent the complaint about 
not being able to handle the SVG file. At that point I ran out of time. I'll get back to it today or tomorrow.
