Thank you Ben for the info.

I've trying to reproduce your package versions, picking up the different
ones from unstable (see below my current versions). I even have removed
gvfs* packages (they are Recommends:, not dependencies) but the bug is
still reproducible here.

However, I'd like to note that I'm using Cut&Paste context menu
operations rather than Drag&Drop to trigger it. With Drag&Drog is hardly
reproducible (I've only seen 1 time since the change to glib 2.46.2-1),
but I can easily crash Thunar simply by cutting and pasting a pair of
small files (a text file and an image file) in other directory.

Agree.I suspect the memory corruption could have several sources, and
the 2.46.2 update fixes a few, but not all.

Also #804816 is suspiciously similar.
