Problem with import of ova file

Hi,
I just downloaded the latest ova images (euroc_c2s1_20141029143118.ova) and tried to import them to Virtualbox (VBoxManage import euroc_c2s1_20141029143118.ova --options keepallmacs).
When I do this I always get the error:

Progress state: VBOX_E_FILE_ERROR
VBoxManage: error: Appliance import failed
VBoxManage: error: Could not open the current file in the OVA package (VERR_TAR_END_OF_FILE)
VBoxManage: error: Details: code VBOX_E_FILE_ERROR (0x80bb0004), component Appliance, interface IAppliance
VBoxManage: error: Context: "int handleImportAppliance(HandlerArg*)" at line 779 of file VBoxManageAppliance.cpp

Is this an error which is related to my host OS? I'm running Ubuntu 14.04 64bit and Virtualbox 4.3.10.

Thanks!

please also download the
euroc_c2s1_20141029143118.ova.md5sum
file and check whether the sums match by executing

Code:

$ md5sum --check euroc_c2s1_20141029143118.ova.md5sum

it should print

Code:

euroc_c2s1_20141029143118.ova: OK

Ok, they are not the same. I try to download the image once again
