If you can reproduce this crash, please file a bug at www.inkscape.org
with a detailed description of the steps leading to the crash, so we can fix it.

Additional info:
- The bug also appeared on Fedora 27 with the version of Inkscape there. I didn't record which one, sorry.
- I'm using Adwaita theme, but the bug also happens with Raleigh (cf bug #1365355).
- I've tried to remove ~/.config/inkscape but the bug remains with the clean user config.
- I currently don't know any workaround that lets me use Flood fill.
