I can confirm this behavior in interpid.
Although, I am not sure about the package. I think bash-completion
returns proper mail: which is taken by bash and displayed as mail\: but
I am not too sure.

I think problem is the file /etc/bash_completion.
at line 3236 it says:
# remove any \: generated by a command that doesn't
# default to filenames or dirnames (e.g. sudo chown)
# FIXME: I'm pretty sure this does not work!
But
