hg_sage.serve() is broken in 4.1.alpha1 (mainly on Mac?)

[jhpalmieri]

hg_sage.serve() works in Sage 4.0.2 but is broken in 4.1.alpha1. On an Intel Mac running OS X 10.5, I see this:

sage: hg_sage.serve()

*                                                *

cd "/Applications/sage/devel/sage" && hg serve --address localhost --port 8200

sh: line 1: 47150 Bus error               hg serve --address localhost --port 8200

*                                                *
**************************************************

Then the web page " http://localhost:8200/" is pretty broken -- see the picture "serve.png".

On sage.math, the web page seems to work, but I get a long list of messages:
