Gnumeric: gnumeric: heap use-after-free when opening a malformed workbook

A heap use-after-free flaw was found in Gnumeric. When a user opens a crafted Gnumeric workbook containing a malformed SheetObjectComponent element, the XML parser can dereference a freed sheet-object component, causing Gnumeric to crash.
