When libgdk-pixbuf-2.0-0 from experimental (2.44.4+dfsg-3) - which uses
glycin-based loaders (libglycin-2-0, glycin-loaders) - is installed, inkscape
immediately crashes on startup:

This is upstream bug https://github.com/bdwgc/bdwgc/issues/802:
gc-8.2.10 crashes inkscape/libglycin
Updating libgc to 9e75f7d from branch release-8_2 fixes this for me.
