Aha! There it is! I should make a comment there.
@lohang It's been quite the while since my last Lubuntu install/use; Inkscape is quite a memory hog, but otherwise lovely, so, to that end, here's a potentially helpful link: http://goinkscape.com/4-ways-to-make-inkscape-run-faster/
@dabnotu As @silkevicious pointed out, this crashing seems to be a known issue in #Lubuntu https://bugs.launchpad.net/inkscape/+bug/1774087
@dabnotu I haven't had any memory leak issues as far as I can remember. Possibly because I run it on LXDE or OpenBox most of the time?
@lohang seems you're not alone...
