Isn't that call issued from the mode-line display? If so, that is
done from redisplay, and redisplay cannot enter debugger, so it
catches all errors. If you want to produce Lisp backtraces from Lisp
code called by redisplay, you need to use the facilities documented in
the node "Debugging Redisplay" in the ELisp Reference manual.
