OK, tracked it down. Turned out to be a combination of circumstances:

 - For some reason as yet unknown, the way we invoke cabal's sdist task
leads to the dist/ subdirectory being included in the tarball. This is
harmless in itself, but led to some relatively long filenames being

 - We repack the archive using the GNU tar, rather than using the one
produced by cabal, to work around a different cabal bug.

 - The tar library cabal uses misreports long filenames encoded in a
certain way which seems to be what GNU tar produces, which made cabal
think it was a tarbomb.

I've worked around it for now by explicitly removing the dist folder
when we repack the archive, and also added an explicit check to the
release process that 'cabal unpack' works.

Beta 3 uploaded to hackage now.
