2006-03-06 Andreas Köhler <andi5.py@gmx.net>
* src/gnome-utils/gnc-html-graph-gog.c: Save the go graph in the
GtkHTMLEmbedded object. Add printing support for the graphs
(depends on #332884). A bit of formatting.
* src/gnome-utils/gnc-html.[ch]: Correct prototype of
GncHTMLObjectCB to return gboolean.
* src/gnome-utils/print-session.[ch]: Create a new job with a
default config for the print dialog. Remove GnomePrintPaper
*paper from the PrintSession.
2006-03-06 Christian Stimming <stimming@tuhh.de>
* src/import-export/ofx/gnc-ofx-import.c: Fix OFX import problem
