oops as an attachment

Attempting to mount:

http://pcdn2-download.vzw.com/mac/7.2/VZAM_7.2.4_2534b_UML290.dmg

with the following command:

mount -t hfsplus -o loop VZAM_7.2.4_2534b_UML290.dmg /tmp/mac290

yields the following oops.  The dmg in question can be extracted with "macutils" dmg2img tool correctly (and then mounted like above) so it's clearly some form of Mac disk image.  However, I'd assume the kernel shouldn't oops when attempting to mount this image.
