Or, posssibly, something *very* weird happens inside gtk_label_set_markup(), maybe if things are already inconsistent at this point.

Anyway, if everything seems right, the last resort is compiling Gtk+ from source, idealy with -O0 to get the line numbers precisely, and running the program with that to see the exact line where the bad typecast occurs.
