Discovered while testing MDL-32680, when opening up the moodle media dialog from tinymce the following notice is seen:

File does not exist: /home/aparup/mcode/pix, referer: http://aparup.moodle.local/integration/lib/editor/tinymce/tiny_mce/3.5/plugins/moodlemedia/moodlemedia.htm

Dan has spotted a '../' miscount somewhere in lib/editor/tinymce../moodlemedia/media.css : line 8 url(../../../../../../../../../pix/a/search.png)
