This is a quite annoying bug - one that has bitten me just recently:

You are correct, it's just an internal hard-coded behaviour of the
GtkLabel with wrapped text. If you just need to have simple label, it
may have sense to implement your own label-like widget.
Otherwise, you should look at gtk_label_ensure_layout function in gtk
sources (there is if (label->wrap) statement). It uses quite hackish
algorithm to determine label's width from layout width, screen width and
so on. Of course, it can be improved. Probably you can suggest something
better. In that case you should search bugzilla for similar bugs,
probably create a bug in bugzilla against gtk and mail a patch to gtk-
