Hi James!
I've installed Marble from Ubuntu Software Center on x64 Ubuntu, so i suppose
it should be 64 bit version.

$marble -v
Qt: 4.8.6
KDE Development Platform: 4.13.3
Marble Virtual Globe: 1.8.3 (stable relase)
(I think I should post it earlier)

I've just found out that it really depends on the globe position. If instead of
"Visible region" I choose "Specify region" N 90, W -180, E 180, S -55,8, then I
get Number of tiles -363284952.
I think in your case you just got the same integer overflow, but the number
just got positive again (the most significant bit became 0 again).
