ports/160422: astro/google-earth: crashes on FreeBSD 9.0

[Juergen Lock]

Some googling found this issue with a very similar backtrace that
is marked `Status:  Outdated', `Closed:  Mar 9':

	https://code.google.com/p/earth-issues/issues/detail?id=1132#c0

There is a comment `This issue is still manifesting on Windows versions.',
maybe someone with an account wants to add another comment (linking to
this PR) that it still happens on FreeBSD too?

Here is my backtrace:  (I first thought this was an nvidia-driver
issue since my only 9 box uses that and I only saw the bug there
and back then I didn't google it enough, but if it even happens on
Windows and the other comment on that ticket says `Several memory
corruption issues were fives in 6.0.1.2032.  Couldn't reproduce
with that version.'... :)
