[Eugen Paraschiv]

Hi,
I'm using jclouds 1.5.0-rc.1 and running into the following, non-critical exception:

As I said, this is simply logged, so it's not critical, but it seems to have been reported before and looks like it's still happening in rc1.
Thanks.

So this is odd, there was no id for the image?  Do you happen to have jclouds-wire.log on this?
