Logstash using protocol => "node" prevents Kibana from finding correct version of ES

[jpbriend]

I installed a fresh new ES version 1.4.0.Beta 1.
Without Logstash plugged in, Kibana checks correctly the ES version.

As soon as I plug a Logstash configured with ES plugin and protocol => 'node', Kibana is blocking on the ES version not seen as 1.4.0.Beta1.
If I configure protocol to be 'http', everything is fine.

Yes, I brought that up here #1546
It's considered not a bug and all nodes (data or client) connected to your cluster must be >= 1.4.

You can work around it by editing line 39666 of the index.js file (inside the jar -- use 7zip to update inside the jar file).
I changed it
from:
if ( versionmath.is('>=' + minimumElasticsearchVersion, versions)) return true;
to:
if (true /*edited*/ || versionmath.is('>=' + minimumElasticsearchVersion, versions)) return true;

Kibana 4 is working great for me even with non-data nodes being an earlier version of ES, but your mileage may vary.
