2.12.1:

2007-10-04  Murray Cumming  <murrayc@murrayc.com>

	* gtk/src/printoperation.hg: Add a custom conversion for the 
	signals that use PrintContext, to fix a reference-counting 
	problem that caused crashes when printing or showing a 
	print preview.
	Note that this was removed mistakenly on 2007-07-14
	(appearing in 2.11.4) so gtkmm 2.10 does not have this problem. 

	* tools/m4/convert_atk.m4:
	* tools/m4/convert_gdk.m4:
	* tools/m4/convert_gtk.m4:
	* atk/src/hypertext.hg:

	* gtk/src/inputdialog.hg:
	* gtk/src/style.hg:
	* gtk/src/textbuffer.hg:
	* gtk/src/widget.hg: Move all signal-specific conversions to 
	the .hg files where they are used, to make this clearer.
