Crash when editing mesh gradient on clone parent

[Antonio Ospite]

Hi,

I am experiencing a crash with Inkscape 0.92.3 (2405546, 2018-03-11) when moving nodes of a mesh gradient of a object that has a clone.

This is on Debian Unstable, with the binary provided by the distribution.

See the attached test file.

Thanks,
   Antonio
