After install inkscape on Ubuntu 14.04 got error "g_variant_parse_error_quark"

What is the output of the terminal commands

uname -a
lsb_relase -a
apt-cache policy inkscape libglibmm-2.4-1c2a

Why are you running GUI applications as root? Especially when it's not needed......

Just example that inkscape not working. I use ruby script for convert SVG to PNG through inkscape.

Example: "inkscape -w 38 -h 38 -f path/to/file -e path/to/file" =>

inkscape: symbol lookup error: /usr/lib/x86_64-linux-gnu/libglibmm-2.4.so.1: undefined symbol: g_variant_parse_error_quark

What is the output of

ldd inkscape

You seem to have certain libraries twice on your system - the current (2.40) version in /lib/x86_64-linux-gnu/ and an outdated (2.39.1) version in /usr/local/lib/ (probably compiled from source)
The loader unfortunately loads the obsolete version, and this most probably leads to your error message.

Is there a specific reason that you compiled that 2.39.1 version from source?

Deleting the duplicate libraries from /usr/local/lib/ should help for inkscape (but has the potential to break other programs if they need that specific verision).

Last advise for remove duplicate libraries helped me. Old version probably was need for "rsvg" tool, that we no use more.

Thanks a lot!
