Package: mediawiki
Version: 1:1.15.5-1~bpo50+1
Severity: normal

Package: mediawiki
Version: 1.15.5-1~bpo50+1

When viewing a MediaWiki page with the Monobook skin in Firefox 9.0, the sidebar ist displayed below the content section (see the screenshot at [0] of the page at [1]).

I found out so far that this behaviour may be caused by 
skins/common/wikibits.js, which detects Firefox 9 as a KHTML-based browser, and applies fixes which make Firefox render the page wrong. The offending lines for that incorrect detection were finally removed in r53348 [2], and specific KHTML detection was dropped in favor of a generic WebKit detection.

Also, I found out, that apparently the following patch fixes this behaviour for Firefox 9:
