Cut dialog crashes on object with multiple shells #3647

Version

1.3.0-dev 2be6e1a84f04e71a2033d2e141b58ca21e4f97ed

Operating system type + version

Windows 10 x64, 32-bit perl (32bit ints) Strawberry Perl 5.24

Behavior

Selecting Cut on provided STL causes a hard crash of Slic3r. STL is manifold, but has 6 (I think intersecting) shells. Thanks Sketchup! No config needed.

Found this by accident; splitting the object permits the cut dialog to start.

@lordofhyphens Great catch! I was begging our print guy Jindra for months to find an example to reproduce the crash on.

Apparently the easiest way to get dodgy STLS is to have Sketchup in your workflow.
