Yes, I've realized that it fails if the variable/AVP stores a SIP URI with "<" 
and ">":

	$var(kk) = "<sip:ibc at domain.com>";
	xlog("L_INFO", " var(kk){uri.host} = $(var(kk){uri.host}) \n\n");

	$avp(s:kk) = "<sip:ibc at domain.com>";
	xlog("L_INFO", " avp(s:kk){uri.host} = $(avp(s:kk){uri.host}) \n\n");

And the log says:

--------------------------------------------------------
ERROR:core:parse_uri: bad uri,  state 0 parsed: <<sip> (4) / 
<<sip:ibc at domain.com>> (20)
ERROR:core:tr_eval_uri: invalid uri [<sip:ibc at domain.com>]
var(kk){uri.host} =  

ERROR:core:parse_uri: bad uri,  state 0 parsed: <<sip> (4) / 
<<sip:ibc at domain.com>> (20)
ERROR:core:tr_eval_uri: invalid uri [<sip:ibc at domain.com>]
avp(s:kk){uri.host} =
--------------------------------------------------------


It doesn't fails if SIP URI doesn't contain "<" and ">".

So I assume that, in my case, it will fail if a UAC generates a "Refer-To" 
with "<" and ">", while it's perfectly valid according to RFC 3515:

  Refer-To: <sip:carol at cleveland.example.org;method=SUBSCRIBE>
