Hi,

I don't really know what is happening there but I can fairly guess it is something related to the domain setting.

Try to not set the domain via setDomain (don't call changeStatus neither) does the issue disappear?

From the message looks like the page has the exception while trying to access itselfs. I guess that's not what actually happens, do your application have more than one frame/iframe?

Also, is the exception actually causing an issue? We've seen some false-alarms in chrome before: http://www.lightstreamer.com/vb/showthread.php?t=597
