Bug description:
Binary package hint: pbuilder

The file /usr/share/pbuilder/pbuilderrc defines:

# Set the debootstrap variant to 'buildd' type.
DEBOOTSTRAPOPTS=(
    '--variant=buildd'
    '--keyring' '/usr/share/keyrings/ubuntu-archive-keyring.gpg'
    )

When we create an armel chroot using pbuilder create, we call build-arm-chroot / qemu-debootstrap. The DEBOOTSTRAPOPTS arg is passed, and it turns out that qemu-debootstrap has trouble parsing the command line arguments if there is a space between the option and the value. This in turn causes the chroot creation to fail later, as we attempt to run debootstrap in the chroot:

Arguably, the command line parsing of qemu-debootstrap should be fixed, but there's nothing wrong or hacky about using the --option=value style of passing arguments to debootstrap. debootstrap itself can handle both styles.
