Inkscape snap crashes when attempting to save

To reproduce:

  1. Start Inkscape
  2. Click File -> Save As

Result: Inkscape immediately crashes with the following errors:

(org.inkscape.Inkscape:2260611): GLib-GIO-WARNING **: 15:44:35.226: Error creating IO channel for /proc/self/mountinfo: Permission denied (g-file-error-quark, 2)

(org.inkscape.Inkscape:2260611): GLib-GIO-ERROR **: 15:44:35.286: Settings schema 'org.gtk.Settings.FileChooser' does not contain a key named 'show-type-column'
Trace/breakpoint trap (core dumped)

As usual for snaps, there is no indication of who I should report this to. In addition, searching for any similar reports is impossible because “inkscape snap” returns 2000 pages of results about the snap feature inside inkscape.
