On http://translatewiki.net/wiki/Thread:Support/Page_last_modified there is:

<pre>
...
( jQuery ) );

}, {"all": ".ui-button{display:inline-block; ... background:#e1e1e1 url(http:

mediaWiki.loader.implement("jquery.ui.core",function($,mw){ ...
</pre>

" ... " is inserted by me and not in the actual code

The "SyntaxError: Parse error" traces back to directly after "http:"

ie. the "" in http: was treated as a comment. I'm not sure whether this is caused by the CSS minifer or by the javascript minifier that ran afterwards.

In the end obviously the JavaScript minifier is the one removing the // comment, but the root cause could be in the CSS minifier.

Possible work around:
Don't minify the end output of load.php (ie. the "mediaWiki.loader.implement" calls), but only run javascript minify on the modules themselfs between { and } of the implemenet() call, and the CSS minifer on what is in the later argument.
Reason being that the call to mediaWiki.loader.load are so simple there's no need to minify them, it would only bring in extra unneeded risks such as the js minifier screwing in the css-string.

Ofcourse that's not a permanent solution as there could be a css string like that inside a module as well such as:

$(el).attr('style', 'background: url(http:// ...
or
appendCSS( 'el { background: url(http:// ...

This is breaking javascript execution completely on some pages of TranslateWiki.net
