I guess nextfile is being freed between being added to the list and then
later being used by the clist.

Try:

	files = g_list_append( files, g_strdup( nextfile ) );

Of course when you're done with "files" you now need to free all the
strings before you free "files". For example, you could do:

	g_list_foreach( files, (GFunc) g_free, NULL );
	g_list_free( files );

You could maybe use GSList instead of GList (if you don't need the
"previous" field).
