Please, include patch from upstream bug https://bugzilla.xfce.org/show_bug.cgi?id=9870
For me, applied via epatch_user on =xfce-base/thunar-1.6.10 works as expected.
Due to upstream unactivity seems this patch is nesessary.
I'm sorry but we're not merging such a major code change without upstream review. We can backport it if they merge it, or at least ACK it on the bug but not before.
this bug is older than 3 years. it is very-very optimistic to expect something from upstream. I've seen a code, it is only for selecting path and it is hard to made code related «selection after delete» worse than now
The ticket was closed as fixed upstream.
