Uncaught TypeError: Cannot call method 'push' of undefined

[GoogleCodeExporter]

What steps will reproduce the problem?
1. No idea. Simply using a webapp on Android that loads some web pages into a 
webview. GoogleTalkback is installed and enabled on the device, which in turn 
runs ChromeVox under the hood.

What is the expected output? What do you see instead?

Through my webapp I visit a logout page that does an http redirect.
On a device without TalkBack enabled, everything works as expected.
On the device with TalkBack enabled, this error is displayed multiple times:

09-13 19:44:45.419    6503-6503/net.megafone.android.webapp D/Web console:﹕ 
Uncaught TypeError: Cannot call method 'push' of undefined -- From line 1451 of 
https://ssl.gstatic.com/accessibility/javascript/android/AndroidVox_v1.js

and the page reloads a lot of times, until it finally loads.

What version of the product are you using? On what operating system?

Please provide any additional information below.

Android 4.1.2 No idea what ChromeVox version, the one that Google Talkback 
loads and injects.

Edit: when I said "this error is displayed multiple times" I meant in the 
console, while debugging.
