Comment 1 for bug 1760493

Edit: It suffices to create an (empty) selection set (in an empty document), then applying any extension (which 'does something', meaning which doesn't leave the document unchanged). Then most actions afterwards (e. g. inserting an object) let Inkscape crash.
Tested with 0.92.3 (2405546, 2018-03-11), Win 8.1.
