createvolume errors

I experienced this problem while creating an EBS volume, using the
latest StarCluster source from GitHub, using python2.7, 32-bit intel Mac 10.6

$ starcluster createvolume 20 us-east-1c

   if itype_platform not in img_platform:
TypeError: coercing to Unicode: need string or buffer, list found

I looked at the comparison (list in string):

itype_platform = static.INSTANCE_TYPES.get(itype) = ['i386']
img_platform = img.architecture = 'i386'

I added a quick fix:

163 if isinstance(itype_platform, list):
164 itype_platform = itype_platform[0]

But then found another problem:

$ starcluster createvolume 20 us-east-1c

   self.instance = res[0]
IndexError: list index out of range

The second time I ran it, it successfully launched the volume. But then,

$ starcluster terminate volumecreator

cli.py:156 - ERROR - failed to load cluster receipt: Incorrect padding

Any idea what is going on?

In any case, I'm working on a mongodb plugin for starcluster. I will
send it with a pull request when I debug it. Thanks for the software!
