AssertionError in provide during builddeb

[Alex Wolfson]

I was building a package from bazaar by
bzr bd --split --dont-purge lp:~adana-team/adana/marvell-restricted-extras

The build host was Marvell's Dove X0 board, running Lucid . (This is ARM board)
Second time command succeeded, but it seems that tar was already downloaded first time

"Looking for a way to retrieve the upstream tarball
Upstream tarball already exists in build directory, using that"

This is the error message from the first run

Need to get 2,115B of source archives.
Get: 1 https://private-ppa.launchpad.net/canonical-arm-dev/marvell-dove-private/ubuntu/ lucid/main marvell-restricted-extras 1 (tar) [2,115B]
Fetched 2,115B in 2s (800B/s)

This looks like it might be because the downloaded filename is different
to the version, but I'm not entirely sure.

Thanks for the pointer to the branch to reproduce.

Thanks,' on another related bug.
