[wp-hackers] Problems using MarsEdit with Wordpress latest nightly (works on one install, not on another)

[Bill Bradford]

(sending this to both the WP and ME lists)

I've got two weblogs:

http://weblog.mrbill.net and http://www.sunhelp.org

Both are using the WordPress 10-06-04 nightly release, pointing to
/xmlrpc.php and using a blog id of 1.

I can retreive/post/etc to SunHELP using MarsEdit (a blogging client),
but when I try to use it with weblog.mrbill.net, I get a "Can't get
recent posts for Another Word For Nerd because The XML parser could
not parse the
data.: XML-RPC Response Parsing Failed."

Any idea what could be causing this problem?  Settings are pretty much
the same for both sites.
