This is in the GTK 2 patch from Daniel Elstner:

I suppose a solution would be:

#  ifdef PANGO_WRAP_WORD_CHAR
	pango_layout_set_wrap(layout, PANGO_WRAP_WORD_CHAR);
#  else
	pango_layout_set_wrap(layout, PANGO_WRAP_WORD);
#  endif

The fallback may be important for very long words.

Anyway, this problem shows that we can anticipate various problems with
various versions of GTK and Pango...  I'll bring out an alpha release
soon, so that these things can be tested.
