Comment 11 for bug 171016

Glad to hear that.

One problem closely related to this is that inkscape mixes stdout with stderr

I work around this with that.

inkscape -z -b white /dev/stdout /dev/stdin 2>/dev/null |
   sed -e '/^DPI:.*$/d' -e '/Background RRGGBBAA:.*$/d'
       -e '/Area 0:0:.*)$/d' -e 's/Bitmap saved as:.*stdout//g' |
   sed -z -e '$s/\\x0a$//g

Hopefully the commits you mentioned also take case of this.
