Status: RESOLVED FIXED

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

Description

[timeless]

Notes:
1. abusedContracts contains:
"@mozilla.org/rdf/datasource;1?name=msgaccountmanager",
"@mozilla.org/rdf/datasource;1?name=mailnewsfolders",
(which shouldn't matter)
2. For some reason Gecko is having a very hard time rendering text using English
characters.

Console output:
###!!! ASSERTION: You are calling CreateInstance
"@mozilla.org/locale/win32-locale;1" when a service for this CID already exists!

I can reproduce this assert if i use javascript:unescape('') and walk past some
problems where the document tries to use iso-8859-1 instead of ISO-8859-1.

I thought there once was a bug for this but i couldn't find it.
