Zero length messages lock up regrowl

[snicker]

working with irssi-growl, for some reason Growl::GNTP seems to send a zero-length message to the server before the actual growl message... this was locking up regrowl and irssi until issuing ^C to regrowl. This caused it to throw an interrupt error.

my hacky workaround is here:
snicker@6e72c6a

The more elegant solution is to probably implement a timeout in that loop

I wonder if this is part of the port scan module that was added, to prevent irssi growl from blocking irssi when waiting for the growl server to respond.

That was my first thought, but I didn't chase that rabbit.
