Possible bug: Breaks tinymce insert episerver image functionality

[AThraen]

I'm seeing something very weird on a client installation. After we switched search to this, there is a glitch when you try to use the "insert image" button in TinyMCE and select from the episerver media library. You can select it fine, but when you are back in the Insert Image dialogue, the Image path is empty.
Some debugging shows that the GetPagedChildrenQuery queryprovider seems to be returning the parameter "previewUrl" as null for all images. It did not do that before the replacement of the search - but I would also be surprised if the search is to blame. It would be great if someone else using epinova search could try it on another installation and let me know if it's a general problem.

So - steps to reproduce: Go to an xhtml text field, click the insert image button, click the Browse button and select an episerver image asset. Click ok and now the url to the image is still empty (but the name is filled out).
