2006-12-19  Federico Mena Quintero  <federico@novell.com>

	Fix https://bugzilla.novell.com/show_bug.cgi?id=226481 - crash
	when the dummy row gets removed.

	* src/file-manager/fm-list-model.c (change_dummy_row_callback):
	Merge patch from http://bugzilla.gnome.org/show_bug.cgi?id=336051.
	See if the dummy row got removed before trying to update it.
