Code review comment for lp:~xaav/loggerhead/export-tarball

> Could you tell me the bug number? Perhaps it would be worth mentioning this in a comment.

I really don't know if the bug has been reported. All I know is if it is changed to .tar.gz, a 500 internal server error occurs and the traceback goes right into bzrlib.

I'm not the only one with the problem, vila encountered the same problem. For more information, see his comment.
