Check the font pointer being NULL to avoid crashes for at least one class
2006-03-01 Tor Lillqvist <tml@novell.com>
* pango/pango-context.c (update_metrics_from_items): Check the
font pointer being NULL to avoid crashes for at least one class of
"bad" fonts (those without a Unicode cmap) on Win32. It would
probably be better to prune out such fonts already in the
enumeration phase. That would require opening (CreateFontIndirect)
every font, though, to be able to check with GetFontData() whether
there is a Unicode cmap. Don't know how much that would slow down
the enumeration.
