200038 - ASSERTION: bad class for Document object

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect)

Description

[Heikki Toivonen (remove -bugzilla when emailing directly)]

I was using Venkman, and when using the twisty to look at the properties of a
document (XMLDocument) object I get this assertion:

###!!! ASSERTION: Bad class for Document object!: 'clazz && clazz->flags & JSCLA
SS_HAS_PRIVATE && clazz->flags & JSCLASS_PRIVATE_IS_NSISUPPORTS', file c:/builds
/mozilla/dom/src/base/nsDOMClassInfo.cpp, line 4825

This is somewhat worrying since the assertion happens in function
documentNeedsSecurityCheck() which we really should get right...!

I got this by placing a breakpoint in nsPolicyViewer.js line 390, then opening
P3P page info tab and clicking Summary button on www.att.net. I am wondering if
this might be regression from the XULDocument refactoring (I have not checked if
this happens in build sprior to that).

Attachment: Fix, we used the wrong JSObject in that assert. Duh!

Nothing wrong with the real code here, just a bug in the DEBUG code.
