images properties have bad values

sometimes devstack runs into an issue where the merge gate fails due to:

    ++ nova boot --flavor 1 --image 9ee73a9a-27d5-42f8-a9d8-1009a09f9586 ex-vol --security_groups=
    ++ grep ' id '
    ++ get_field 2
    ++ read data
    ERROR: Can not find requested image (HTTP 400)
    + VM_UUID=
    + die_if_not_set VM_UUID 'Failure launching ex-vol'

after SSH-ing in I can explore glance:

    cd /opt/stack/devstack
    . openrc

glance has 3 images:

    $ glance index

But the image properties of the ami:

the ramdisk is missing some data and has junk at the end of it.

In the devstack install log you can see the ramdisk id isn't retrieve correctly:

It seems that glance putting percentages is breaking our ability to grab stdout?
