Konqueror: no preview in tooltips

Hi, when hovering a file in konqueror I don't get file previews in tooltips even if I've enabled all relevant options :( This is a fresh snapshot from git. Here is the relevant error message from the xsession-errors log: kio (KTrader): query for ThumbCreator : returning 6 offers kio (KService*): Request for unknown property 'MimeTypes' kio (KService*): Request for unknown property 'MimeTypes' kio (KService*): Request for unknown property 'MimeTypes' kio (KService*): Request for unknown property 'MimeTypes' kio (KService*): Request for unknown property 'MimeTypes' kio (KService*): Request for unknown property 'MimeTypes' Any clue?
