caja-actions crashed with SIGSEGV in na_selected_info_is_owner()

[Nathanael C. Higley]

I installed caja-actions to add a custom srm - aka Secure Wipe action and I restarted my fully updated focal - devel system to activate the caja-actions extension, however when I started caja and selected a "test" folder caja crashed on me.
