You can see the problem on http://n9wiki.de which uses MediaWiki 1.18.1. The first time the page is shown in browser everything looks fine and the (Vector skin) CSS is used correctly. If you reload the page You see the same content but looking very ugly because all styles are gone. If you press Ctrl+F5 (at lest in Firefox) to clear the browser cache completely and reload the page it's shown correctly again. Please let me know if you need more information. If this bug is fixed in trunk please let me know what exactly was fixed.
I tested the behaviour on Ubuntu 11.10 (Firefox) and Windows XP (Firefox, Chrome). The server is running Debian 5.0.0: http://n9wiki.de
The error log shows the following error: [Wed Feb 01 10:29:03 2012] [error] [client 80.149.113.197] FastCGI: comm with server "/srv/www/fcgi/n9wiki.de/php5/php-fcgi-starter" aborted: error parsing headers: duplicate header 'Status', referer: http://n9wiki.de/index.php?title=Hauptseite
Created attachment 9935 [details] http log containing errors The attached log contains the http communication between browser and server. GET /load.php?debug=false&lang=de&modules=skins.vector&only=scripts&skin=vector&* HTTP/1.1 [..] HTTP/1.1 500 Internal Server Error [...] and so on
HTTP/1.1 500 Internal Server Error means PHP died out somehow. You have to look at the log file where PHP errors are logged.

Id did and got the following error message: [Wed Feb 01 10:29:03 2012] [error] [client 80.149.113.197] FastCGI: comm with server "/srv/www/fcgi/n9wiki.de/php5/php-fcgi-starter" aborted: error parsing headers: duplicate header 'Status', referer: http://n9wiki.de/index.php?title=Hauptseite
Is Bug 12124 related?
Sorry I mixed up your error logs. Indeed, your issue looks like a duplicate of bug 12124.
*** This bug has been marked as a duplicate of bug 12124 ***
I don't think that it is an exact duplicate of Bug 12124. I tried the workaround which was provided there without any success. Maybe there is an other place where more than on header is generated? A I am not a developer my possibilities are limited and I am not sure what to do. I'll try to install an older version of Mediawiki to see if the same Bug appears.
...please have a look to my comment in Bug 12124. This Bug should get a correct Mediawiki version and subject if it stays as a duplicate of this one! Thanks
Other peoples seem to have the same problem : http://www.mediawiki.org/wiki/Thread:Project:Support_desk/css_broken_on_my_wiki
Please look at your php error log, not the apache error log.
