Emacs is trying to open a socket to host lucretia on port -29892.
The port number is invalid, hence the error.

The bug is probably in epmd-recv-port-resp where decoding the port
number from epmd out of an emacs buffer and into an integer is going
awry. This is a common sort of problem when keeping binary data in
Emacs buffers: you get a lot of unwanted problems with conversions
when Emacs wants to intepret the contents of buffers as encoded
characters instead of plain bytes.

Hopefully the crowd of Emacs hackers coming to Erlang as part of the
general influx will make short work of this and other bugs! I'd
enjoying a break from serious Emacs hacking myself :-)

Cheers,
