1.0 is a release candidate. Romain is using the unstable version of 
Debian (sid), so he's using Inkscape 1.00rc.

Anyway Inkscape 0.92 will be around for some time, so a better solution 
would be defaulting to the export option of the current version of 
Inkscape unless the user sets an environment variable (INKSCAPE_VERSION?).

So a test of an environment variable instead of spawning a process to 
run "inkscape --version".
