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

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; ru; rv:1.8.0.2) Gecko/20060308 Firefox/1.5.0.2
Build Identifier: Xulrunner trunk 2006-05-02

I get an error trying to embed Gecko built from Xulrunner trunk. This error began to occur only recently.

It looks like it's repeatedly trying to register the "DOMParser" class name, and probably others, in the script namespace manager.

Below is a call stack copied from the Visual Studio 2005 debugger:

Reproducible: Always

Peter, this looks like fallout from moving this stuff to content somehow?

Comment 2

[Peter Van der Beken [:peterv]]

Probably some stuff remaining in the categories for DOM classes. Nuking the component registry should help.

Yes it did. Should the bug be resolved now?

Comment 4

[Boris Zbarsky [:bzbarsky]]

Yeah, a stale component registry is going to do this...
