AMI Parser Syntax Error

#128

I was playing around with the AMI connection in a script. I set the events callback to a proc that just puts the events on STDOUT. Then shortly after connecting I started seeing this:

ERROR ami: ADHEARSION'S AMI PARSER ENCOUNTERED A SYNTAX ERROR! PLEASE REPORT THIS ON http://bugs.adhearsion.com!

So I am reporting it hear as requested. Below is a copy of the output. If you have any questions please just email me directly.

A few more details please:
- What version of Asterisk are you running?
- How did you initialize @ami.conn?
It's a bit hard to follow the original problem report because the pasted text gets interpreted as formatting. Would you mind editing the original post and wrapping it in "@@@" code blocks? See [Formatting help] for more information.

My Asterisk server is a Vicidial build

[root@dialer ~]# asterisk -V Asterisk 1.4.27.1-1 RPM by demian@goautodial.com

I am initializing my manager connection like so:
```
ManagerInterface.class_eval do
  attr_accessor :event_callback
end

mi = ManagerInterface.connect ({
  :host => "127.0.0.1",
  :username => "user",
  :password => "pass",
  :event_callback => proc {|e| puts e}
})

@ami = Ami.new(mi)
IRB.start
```
FYI: I am not seeing this problem any more. I think that parse just got in a weird state. You can see from the output that in some cases it is missing the first char of the message. For example:

ERROR ami: ... OFFENDING TEXT:
"vent: PeerStatus"

- State changed from new to invalid
Thanks for the update. If it happens again, please feel free to re-open this ticket. But since it does sound like the parser just got in a weird state for unknown reasons, I'm closing this for now.
