TYPO3 Core

have a look at the attached screenshot.

Steps to reproduce:
-add a DB Mount to an BE-User, press the red arrowbullet on a page (not on root)

Problem is using of the returnValue of t3lib_iconWorks::getSpriteIconForRecord('pages', $mainPageRec), which is a complete span tag. This tag is insert in the onclick JavaScript Statement insertElement.

function insertElement(table, uid, type, filename,fp,filetype,imagefile,action, close) { //
var performAction = true;
// Call performing function and finish this action:
if (performAction) {
addElement(filename,table+"_"+uid,fp,close);
}
return false;
}

in this case the imagefile is never used, so don't give over the imagefile to the javascript.
