	* src/eval.c (intersects): Typo fix.  Sheet was being assigned
	instead of being tested for equality.  This got Michael to crash
	Gnumeric (as there was no test for can_remove)

	* ms-excel.c (ms_excel_workbook_detach): Check the return value of
	workbook_detach_sheet.
	(ms_excel_read_sheet): If detaching fails, there is a dependency.
