SVG file causing cairo to segfault

There is a bug report [1] in Arch Linux from a user who is seeing xfce4-panel
segfaults when using the Faenza icon theme and specifically the icon for the
Geany application.

I have attached a modified geany.svg which is reduced to a single path.
Converting it to the PNG format using rsvg results in a segmentation fault.

E.g.:

$ rsvg-convert geany.svg -o geany.png -w 40
Segmentation fault
$ rsvg-convert geany.svg -o geany.png -w 10 (this size works correctly)
$ rsvg-convert geany.svg -o geany.png -w 16
Segmentation fault

cairo is compiled with gcc 4.7; maybe this matters.
