UPGRADING and NEWS
Fix typo
When src->src is null this doesn't get initialized
but it is still used, so the passed in *ze will point
to unitialized memory. Hopefully src->src is never
null, but just in case this initialization doesn't hurt.

Fix coverity issue with -1 returned by findOffset not being handled by getPreferredTag
fix memory leak on error (from Coverity scan)
