When I try to export a simple plot

figure();
plot([0,1],[0,1],'x');
print 'test.svg' -svgconvert


Octave runs forever and creates a huge temporary file that quickly becomes >
100 GByte if I don't kill the process. The GPU runs on 50% load and two out of
8 physical cores are on 100% load.

When I copy the temp file before stopping octave, I can see that it is
svg-code.

... sequence never ends


After a normal svg header I get a sequence of infinite polygon fills with
"crispEdges".

After adding the -nosvgconvert option to print command the problem persists.
