When line wrapping is enabled (label.set_line_wrap(True)), GTK restricts
labels to an arbitrary size, rather than utilising the entire allocated space.
This has been known upstream since 2005 (GTK#318276 [1]), but remains unfixed
to date.
Work around this bug by using a size-allocate signal handler that sets the
requested size of the label to the actual allocation.

Could it be that the issue is fixed in GTK+ 3 and introspection? I have
attached two examples.
