Crash when attempting to edit a "non-contiguous" path

[Erin Spiceland]

My first bug report here. I'm a total Inkscape newbie.

I followed the tutorials and began creating paths. I have a path that I thought was contiguous by the colloquial definition of "contiguous." In attempting to make the snake's nose more curved up, Inkscape crashed. I've repeated this three times and gotten a screen capture of it. To repeat, zoom in on the snake's nose and try to reshape the bridge.

Console error printed during crash:

terminate called after throwing an instance of 'Geom::ContinuityError'
  what(): lib2geom exception: Non-contiguous path (/build/inkscape/parts/inkscape/src/src/2geom/path.cpp:1043)

Emergency save activated!
Emergency save completed. Inkscape will close now.
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.
terminate called recursively
Aborted (core dumped)

Where can I find the core dump? It's not in the directory I called inkscape from.

Here's the video of the steps to reproduce. https://www.youtube.com/watch?v=ORQJYBAcynE&feature=youtu.be
