PPA package rejected for encoding errors

[Gael Varoquaux <gael.varoquaux@xxxxxxxxxxxxxx>]

Hi,

I am getting my upload to my PPA rejected for encoding errors. This is
actually a package backported from debian with no change to the source
package.

I already had this problem a while ago and signaled it on this mailing
list. Someone told me he would have a look at it. I didn't worry, but now
it is pretty bad, because there is no installable version of the package I 
am trying to upload. I uploaded a version with a bug, and ran into this
problem trying to fix it. Than I deleted the bugy version, but the
previous version is not visible to users, as it has been superseeded. I
am now trying to upload the very exact package that I succesfully
uploaded earlier, but failing. I must be doing something different, but I
can't figure it out.

I am one of the upstream developpers of this software (amayvi2). With
have been advertising this PPA as a distribution mean to get the latest
version of the software (I am working in close coordination with Debian
and Ubuntu maintainers, but I don't expect Debian and Ubuntu to track the
software on a weekly basis, especially since we are in beta. However the
differences in features between the version in Ubuntu and this one is
huge, so this PPA is fairly important to our users.

What are my options?

Please Cc me in answers, as I am not subscribed to the list.

Thanks,

Gaël
