When copying data to the clipboard using the following code the clipboard is empty.
function copyData(thumID) {
    netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
    var clip = nsCC["@mozilla.org/widget/clipboard;1"].getService(nsCI.nsIClipboard);
    if (!clip) return false;
    var trans = nsCC["@mozilla.org/widget/transferable;1"].createInstance(nsCI.nsITransferable);
    if (!trans) return false;
    var transferString = createTransferableGraphic(thumID);
    var strGraph = nsCC["@mozilla.org/supports-string;1"].createInstance(nsCI.nsISupportsString);
    if (!strGraph) return false;
    strGraph.data=transferString;
    trans.addDataFlavor("text/x-my-specific-xmldata");
    trans.setTransferData("text/x-my-specific-xmldata", strGraph, transferString.length*2);
    clip.setData(trans,null,clip.kGlobalClipboard);
}

After invoking the method on Windows OS the clipboard is not empty, but it is empty on MAC OS.

Reproducible: Always

Steps to Reproduce:
1. Create clipboard instance:  var clip = nsCC["@mozilla.org/widget/clipboard;1"].getService(nsCI.nsIClipboard);
2. Create transferable object: var trans = nsCC["@mozilla.org/widget/transferable;1"].createInstance(nsCI.nsITransferable);
3. Create data to transfer: var transferString = createTransferableGraphic(thumID);
4. Create transferable data object: var strGraph = nsCC["@mozilla.org/supports-string;1"].createInstance(nsCI.nsISupportsString);
5. Add your specific data flavor to transferable object and fill it: trans.addDataFlavor("text/x-my-specific-xmldata");
    trans.setTransferData("text/x-my-specific-xmldata", strGraph, transferString.length*2);
6. Put the data to the clipboard: clip.setData(trans,null,clip.kGlobalClipboard);

Actual Results:  
The clipboard is empty on MAC OS.

Expected Results:  
The clipboard should contain data to transfer.
