unable to start a cluster created with starcluster: NoneType object is not iterable

From: Jeffrey Wan <no email>
Date: Tue, 6 Mar 2012 14:39:23 +0000

Hi,
I could not start or ssh in my cluster created by starcluster quite often recently.
The screen logs and the crash report content is attached in this email.
Could you kindly give me some clue?
And oddly, I could not find many useful information from the Internet?
Thanks!

Thanks!
