P: Publish to Hard Drive in Format Original does not create XMP Sidecars (LR 3.4.1)

LR 3.4.1, Win7 64-Bit:
Publish to Hard Drive in Format "Original" no longer creates XMP sidecar files along with the published originals.

Steps to reproduce:

•  
• Create new Catalog
•  
• Automatically write Changes into XMP not checked
•  
• Import some .cr2 files
•  
• Export .cr2 images in format "Original" to an export folder
•  
• Create Published Collection, using format "Original" to a publish folder
•  
• Drag a couple of images into the Published Collection
•  
• Publish the collection
•  

Actual Result:

•  
• Images exported as originals show up with .cr2 and XMP sidecar files in export folder
•  
• Images published as originals show up with only .cr2 files (no XMP sidecar files) in published folder
•  

Expected Result:

•  
• Images published as originals should show up with .cr2 and XMP sidecar files in published folder
•  

The same procedure in LR 3.3 produces Raw and XMP files in both export and published folders.

As I don't have LR 3.4 installed anymore, I cannot try with LR 3.4, but maybe somebody who still has it installed can.
