Good news. They have marked this bug as a duplicate of https://bugs.gnucash.org/show_bug.cgi?id=796733 which has a workaround. If I start Gnucash in Qubes as follows: $ GTK_IM_MODULE=ibus gnucash the crash goes away, and now the delete and backspace keys also work. This saves me a lot of headache. I was otherwise looking at an immediate migration to ledger, as there does not look like there will be a fix anytime soon. Weird that ibus / input method usage b0rks Gnucash on QubesOS VM but not on my bare metal install. Some kind of X interaction going on there, I bet. If you are at Debconf, so am I.
