Comment 16 for bug 198493

I'm investigating this and if I send the same presence element I don't see that Growl gets activated. Note that coccinella needs to be in the packground for Growl to display anything. If I use another coccinella instance on another machine and select the same presence:

<presence from='d\<email address hidden>/Coccinella@hp' <email address hidden>/Coccinella@Macintosh' xml:lang='en'>
  <status>Vikigt möte</status><show>chat</show> (Swedish)
  ...
 First time it Growl gets activated, next time with identical presence it doesn't. Note also that there is no explicit type='available' attribute since this is by default, and xmpp says to exclude it in that case (bandwidth).

The code that sends the "signal" looks like:
    # Hook to run only for new presence/show/status.
    # This is helpful because of some x-elements can be broadcasted.
    array set oldPres [$jlib roster getoldpresence $jid3]
    set same [arraysequalnames attrArr oldPres {-type -show -status}]
    if {!$same} {
 eval {::hooks::run presenceNewHook $jid $type} $opts
    }

and the Growl posting has been changed to:
 set title $djid
 set msg $showMsg
 if {$status ne ""} {
     append msg "\n$status"
 }
 growl post [mc Status] $title $msg $cociFile

which makes better sense.

Note really sure what goes wrong in your case. I also tested using escaped ("\") JID and that works too.
