Rrror: jQuery.event.specialAll[type].teardown is undefined

[rentzsch]

Reproduction:

1. Load ​http://rentzsch.com/share/jQuery_1.3_teardown_undefined.html in Firefox.

2. Reload the page.

Expected:

• Page reloads normally.

Actual:

• An error is logged:

  Error: jQuery.event.specialAll[type].teardown is undefined
  Source File: http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js
  Line: 2561
  

Environment:

• Mac OS X/Intel 10.5.6

• Firefox 3.0.10

Regression:

• Does NOT appear in 1.2.6.

• DOES appear in 1.3.

• DOES appear in 1.3.1.

Notes:

• "Bob" has the same issue on Firefox 3.0.10 on Ubuntu: ​http://groups.google.com/group/jquery-dev/msg/0996558bbedae24a

• Coda 1.6.4, which uses WebKit, reports 2561: Undefined value upon reloading the page. So this bug doesn't look Firefox-specific.

• The Object.prototype.getFoo assignment seems critical. It appears upon removing the click handler, the machinery gets confused and thinks getFoo() is also an event handler, which it fails to remove.

The same problem occur in Chrome 3.0.182.3 under Windows XP SP3.

Yes, jQuery does not support code that modifies Object.prototype. There are several discussions of this on the dev group. It may be supported in the future but is not supported now.
