How to trace: "The sanitizer was unable to parse the following block of html: <32"?

Question

Error: [$sanitize:badparse] The sanitizer was unable to parse the following block of html: <32
http://errors.angularjs.org/1.2.18/$sanitize/badparse?p0=%3C32

    at Scope.$apply (http://localhost:3000/assets/angular.js?body=1:12661:24) 

I am aware that it is because of the following issue: http://errors.angularjs.org/1.2.18/$sanitize/badparse?p0=%3C32

"This error occurs when the HTML string passed to '$sanitize' can't be parsed by the sanitizer. The error contains part of the html string that can't be parsed.

The parser is more strict than a typical browser parser, so it's possible that some obscure input would produce this error despite the string being recognized as valid HTML by a browser."

My question is: how to trace this problem? From the stack trace alone, none of them refers to my code. Is there any tools which can help tracing this issue?

You can use Chrome Developer Tools (CDT) to catch caught JS exceptions (check "Pause on Caught Exceptions" checkbox in CDT). That may give you more information about your issue.
