Source tarball corrupt (prevents deployment to AppHarbor) (BB-3353)

Hi,

I'm having trouble with deploying a project to AppHarbor as the tarball that the AppHarbor guys are fetching from BitBucket is corrupt.

It looks like it's something specific to a particular repository (my uglybugger.org project) as my others seem to be working fine. It's verifiable outside of AppHarbor, too - just downloading it from the "get source" menu fetches a broken archive.

For an example of the broken tarball, try opening this one:
https://bitbucket.org/uglybugger/uglybugger.org/get/245aa0bc8522.tar.bz2

I've tried deleting the repository, re-creating it then pushing all my changes back but I get the same result.
