Look for the 'browser.js' file in Opera's setting directory, it contains  
some javascript that's run for every page you visit, to fix  
incompatibilities with Opera. If you search for 'Prototype fix' in that,  
you'll find the code that causes this message. It looks like it's  
replacing Opera's implementation of Array.prototype.concat with one that  
works better with Prototype - Prototype seems do the same thing itself in  
recent versions. Probably nothing to worry about.

Hope that helps,

Daniel
