It should not be specific to git; We're configured to use the same
script as before git-hooks transition to email the updates. Here is
the command we use:

    /sourceware/infra/bin/email-to-bugzilla -G 'gdb binutils'

(the contents of the email is piped via stdin)

I suspect either authentication, or schema changes causing
the breakage (total guess, though).
