I'm also getting this problem. Only in dev mode, and only when the page is returning from an external page.
On our situation, we are doing OAuth. So we redirect to an external site to login, then when the external site returns, the first RPC call throws a IncompatibleRemoteServiceException. The only way to get it working again, is to restart the GWT server. Refreshing, or closing and opening the browser, does not fix it. GWT 2.5.1, Eclipse, Java 1.7.
