Converters: Skip Qt's loadable svg function

[Vincent van Ravesteijn]

Previewing of some (most) svg files does not work anymore even if Inkscape
and the converters has been set correctly. This is because Qt claims to be
able to load svg files natively. However, Qt does a bad job doing that.
Therefore, I want to use my configured converter. How can I do that ?

I now applied the attached patch, but it might not be everyone's choice.
