#18 Intermittent error popup when using Chrome in dev/hosted mod

[Amit Chatterjee]

On Chrome: seen after answering a call and sending a canned message, if you type in a message and send,
error message below is output. Popup message said something to the effect that a Java Object was expected.
Difficult to reproduce.

FINE: Received response from the server. Number of messages received = 1
