Don't think this is the problem (I don't have access to Opera at the moment) 
but the google maps API v3 does not officially support Opera:

https://developers.google.com/maps/faq#browsersupport

=======================================================
Which web browsers does the Google Maps JS API support? 
The Google Maps JavaScript API supports the following web browsers: 

Google Maps JavaScript API V3:

IE 7.0+ (Windows) *
Firefox 3.0+ (Windows, Mac OS X, Linux)
Safari 4+ (Mac OS X, iOS)
Chrome (Windows, Mac OS X, Linux)
Android
BlackBerry 6
Dolfin 2.0+ (Samsung Bada)

Looks like ZipFile.complete.js has a problem in Opera:

sig: 4915280 (0x4B0050)
ZipFile.Signatures.Entry: 67324752 (0x4034B50)

Results in "WARNING: this file does not appear to be a zip file"

This "patch" works in Opera:

/* patch for Opera */
  if (/opera/i.test(navigator.userAgent)) {
fixedArray = new Uint8Array(binStream.length/2);
    for (var i=0; i<binStream.length; i+=2) {
        fixedArray[i/2]=binStream.array[i];
    }
binStream.array = fixedArray;
    binStream.length = binStream.length/2;
}
/* end patch for Opera */

Test version of ZipFile.complete.js containing the patch is here for now:
http://www.geocodezip.com/geoxml3_test/ZipFile.complete.js

Let me know if it works for you.

Still hoping for a more elegant fix (or acknowledgement that this is a bug in 
Opera).

Updated the "patch" to include verification that the problem exists before 
fixing it, just in case the problem gets fixed:

/* patch for Opera */
if (/opera/i.test(navigator.userAgent) && 
    // make sure it is still broken,
    // the first 4 bytes will contain the zip file signature
    // for the geoxml3 use case (so bytes 1 & 3 will not be 0)
    (binStream.array[1] == 0) && (binStream.array[3] == 0))
{    
    fixedArray = new Uint8Array(binStream.length/2);
    for (var i=0; i<binStream.length; i+=2) {
        fixedArray[i/2]=binStream.array[i];
    }
    binStream.array = fixedArray;
    binStream.length = binStream.length/2;
}
/* end patch for Opera */

This is a bug in Opera 12

http://stackoverflow.com/a/11322464/1210329

Should be fixed in Opera 12.01

Setting the MIME type to application/octet-stream as suggested here:

http://stackoverflow.com/questions/11284728/how-do-i-access-8-bit-binary-data-fr
om-javascript-in-opera

worked (when put in the right place). Committed that change Revision 83.
