[tex-live] dvipdfmx warnings -- sensible or not?

Since many folks with lots of PDF knowledge are on this list, I'm 
asking this here. ;-)

I have a PDF file with a page that I include in a TeX document, 
using dvipdfmx. This driver outputs warnings:

** WARNING ** "TrimBox" different from current CropBox found.
** WARNING ** TrimBox (PDF): [ 0 0.055 595 841.945 ]
** WARNING ** CropBox/MediaBox (PDF)   : [ 0 0 595 842 ]

I can't see the problem that might be a reason for this warning. 
According to my understanding, it is quite normal that a TrimBox is 
smaller than a CropBox or a MediaBox -- that's explained in the PDF 
reference manual.

In addition, dvipdfmx behaves itself reasonably; the trim box is 
used as bbox of the constructed form object.

I will prepare a patch to dvipdfmx anyhow, that will add support 
for TEX_HUSH configuration; now I'm asking for your opinion if one 
should discard this warning as well. Or, you could please explain 
the problem to me, why this situation might warrant a warning.

Thanks in advance for any answer,
