When testing changes I was making to the auth language files I found that the `curlcache` string in de_utf8/admin.php is causing multiple notices to be shown.

Notice: Trying to get property of non-object in /var/www/m20.dev1/moodle/lib/moodlelib.php(5960) : eval()'d code on line 117

+ several more (note the CFG one)

The error can be replicated by simply logging in, changing your language to `de` and then browsing to the admin section.

The error is (I believe) caused because $a is used several time throughout the string sometimes as an object, sometime just '$a'. I'm not too sure what $a is meant to be and as I don't speak that language I really have no clue what is going on. If someone who understands de this could please check it and make a decision about what it should be a fix it that would be fantastic
