Comment 2 Vincent Untz 2005-12-15 21:43:01 UTC

Fixed in HEAD. The theme is broken, though: the panel is all black. I could
workaround it, but I don't think we should. Problem in theme is:

style "panelbg" {
  bg_pixmap[NORMAL] = "<parent>"
  bg_pixmap[INSENSITIVE] = "<parent>"
  bg_pixmap[PRELIGHT] = "<parent>"
  bg_pixmap[SELECTED] = "<parent>"
  bg_pixmap[ACTIVE] = "<parent>"
}

	Don't crash with some themes. Thanks to Benjamin Berg for helping.
	Fix bug #320602.

	* panel-background.c: (panel_background_prepare): look if the pixmap
	is GDK_PARENT_RELATIVE and do what is necessary in this case
	(panel_background_set_default_style): don't ref/unref pixmap if it's
	GDK_PARENT_RELATIVE
	(panel_background_free): ditto
