Eucalyptus returns 403 with valid credentials on image registration

[Gustavo Niemeyer]

Eucalyptus was returning a 403 error during an image registration even when everything was apparently correct.

The commands executed were:

euca-bundle-image --user 000100729354 --image /tmp/image-store-proxy/download/http%3A%2F%2Flocalhost%3A52781%2Fimages%2Fkernel --destination /tmp/bundle --kernel true
euca-upload-bundle --manifest /tmp/bundle/http%3A%2F%2Flocalhost%3A52781%2Fimages%2Fkernel.manifest.xml --bucket foobar
euca-register foobar/http%3A%2F%2Flocalhost%3A52781%2Fimages%2Fkernel.manifest.xml

Bundling and uploading worked fine, but registering the image returned the 403.

After some time and following an advice from Neil, I renamed the manifest to a shorter "normal" filename, and it worked correctly, confirming that credentials were correctly set. I don't know if it was just a coincidence that the filename helped or if indeed it was refusing for some other reason.
