Opera 10.10 Javascript Errors

[frogman]

Just curious if anyone that uses version 10.10 of Opera ever experiences the odd Javascript error when say clicking on widgets etc in blogger, this error below was found while attempting to click on a blogspot widget, however no great issue as there is an option to stop showing the errors, and when I clicked on OK to remove the message the page appeared as normal.

ERROR: Possible problem with your *.gwt.xml module file.

The compile time user.agent value (opera) does not match the runtime user.agent value (unknown). Expect more errors.
