Ah thanks, I'll look at it. (I had not noticed your patch when I wrote the above). But 
even if it works I'd prefer to ask the dev of dvisvgm first for his expert opinion on this 
patch. I've already asked him actually.

Given the complexity and the integrated nature of the texlive build environment, that 
would probably be hard to achieve locally. A cleaner approach would be to (temporarily) 
package dvisvgm separately and disable it in the texlive-bin configuration. I'll contact 
you offlist on this if this becomes a necessity ;)

Rémy, thanks for the patch btw ;)
