Renaming nef files does not rename corresponding xmp files.

Question

I just renamed all my files using Lightroom (select all; rename files)
Unfortunately, this did not rename the correponding xmp files. Since this is irrevercible, I'm now in a tight spot. I'm stuck this thousands of files with "lost" xmp files
Is this a known bug? If not, how do I report it as a bug?
(Also, it is very annoying that the renaming changes the file creation dates! This pretty much destroys my backup routine..)

Regarding your screenshot: I see the modified date is before the creation date.. That implies that the file was copied after it was created (that's standard windows behavior - more here if you're interested: http://www.techrepublic.com/article/build-your-skills-learn-to-manipul ate-file-time-stamps-in-windows )
This behavior is excactly what I'd hope LR wouldn't have. I'm guessing LR renames by copying the file and deleting the original - failing to update the new file with all properties of the original file.

I think you are misunderstanding the screenshot. Lightroom renaming has no effect here, all the dates/times shown are 10 days before I renamed them with the sequence number. In other words, there is no "copy then delete the original", Lightroom uses the OS to handle file system-level changes, and "rename" retains all original date properties. When I renamed them using Lightroom, nothing was changed apart from the file-name.
"Date Modified" will normally be before "Date Created" unless shooting tethered, as after capture the image is subsequently copied to hard drive....that subsequent copy retains the original Date Taken and Date Modified values, but the copy will have (as you say) the Date Created set to the (usually) later system time. In this instance the card was removed from the camera immediately after the shots were taken and the images imported into Lightroom, which explains the small one minute difference between Date Modified and Date Created. But you shouldn't interpret that time difference in any other way, it is entirely normal and expected.
