[DRE-maint] Bug#652802: Reproduced on Ubuntu

[Fabrice Coutadeur]

Hi,

The package is FTBFSing also in Ubuntu, with the very same error:
...

/usr/bin/ruby1.8 -I/usr/lib/ruby/vendor_ruby
/usr/lib/ruby/vendor_ruby/gem2deb/test_runner.rb

E: Build failure (dpkg-buildpackage died)

I'm using sbuild to build the package locally, on an AMD64 clean
chroot, and I can post the full build log, if you want.

Thanks,
