Feel free to upload directly to the ubuntu-multiseat PPA if you want.
It's OK if the package hasn't been fully tested before doing so -- I
think it's reasonable for users of the PPA to expect some problems on
occasion, and it'd be nice to get as wide of a testing audience as
possible.  It's good to push the burden of testing onto others so that
you have more time to develop.

This sounds vaguely familiar and I can't remember why.  A search for bug
reports only turned up the one you filed yesterday.

Are you only seeing this with uploads to a PPA?  I've had problems with
some of the builders.  You could try building it locally on your own
machine to see if you can reproduce the problem.  I use pdebuild with
the attached .pbuilderrc like so:

    dist=$(lsb_release -cs)

    # these steps only need to be done once
    sudo pbuilder --create
    cat <<EOF | sudo tee /etc/apt/sources.list.d/pbuilder.list
    deb file:/var/cache/pbuilder/result/${dist} ./
    EOF

    # if it has been a while since I last updated the base.tgz
    sudo pbuilder --update

    # get the package I want to modify and build
    dget -u 'url://to/package.dsc'
    cd package

    # make edits as desired

    # bump package version
    dch -i

    # build the package
    pdebuild

    # install the package
    cd /var/cache/pbuilder/result/"${dist}"
    dpkg-scanpackages . >Packages
    sudo apt-get update
    sudo apt-get upgrade

Hope this helps,
Richard
