Aah, I finally found out why I could not reproduce it, and what's wrong.
I have local MTAs on all my boxes. If I install a system without one, I
can replicate the error. It apparently tries to send a mail to the admin
about the error and dies with a SIGPIPE:
Program received signal SIGPIPE, Broken pipe.

This looks suspiciously similar to bug 193516.
I'll take a stab at this now.
** Summary changed:
- sudo shouldn’t ABSOLUTELY NEED to look up the host it’s running on
+ sudo fails if it cannot resolve the local hostname and no MTA is installed
