Subject: document.createElementNS is null or not an object in IE8
X-Git-Tag: 1.31.0-rc.0~16223^2
X-Git-Url: http://git.cyclocoop.org/%22%2C%20generer_url_ecrire%28?a=commitdiff_plain;h=cd361413d80a6af61991da642ace1c12130d2c0f;p=lhc%2Fweb%2Fwiklou.git

document.createElementNS is null or not an object in IE8

Having $wgDebugToolbar = true and visiting the wiki with IE8 will give
no debug toolbar, using ?debug=true gives a "document.createElementNS is
null or not an object" javascript fatal.

Throw a error. The function 'createSvgElement' will never be called,
because profiling gives a "An ES5 compatible javascript engine
is required for the profile visualization." in IE8.
