File Embed function breaks WYSIWYG editing on recent Google Chrom(e)(ium)

When I enable the File Embed module of File Framework, the WYSIWYG editing function provided by the WYSIWYG module is broken on Google Chromium (the daily builds). The following output is produced in the Javascript console:

/sites/all/libraries/tinymce/jscripts/tiny_mce/tiny_mce.js?e:1Uncaught TypeError: Object function (obj) {
for(var i=0; i if(this[i] == obj) {
return i;
}
}
return -1;
} has no method 'indexOf'
/sites/default/files/js/js_124137edc4ddd9437cbe817c81c391b8.js:198Uncaught TypeError: Object function (obj) {
for(var i=0; i if(this[i] == obj) {
return i;
}
}
return -1;
} has no method 'substr'

The issue occurs only in Google Chromium; Firefox works just fine doing the same thing.
