Invalid value '1.0' for attribute 'version' on element 'Envelope'

I have an OVF from VirtualBox that I want to import into VMware Workstation 6.5.2 (linux). The first thing I noticed was that there is no 'Import' option in the File menu of VMware 6.5.2 for linux. So, I ran the ovf file through ovftool. ovftool reported an error when converting:

~/tmp] ovftool foo.ovf ~/tmp/convert/foo.vmx

Opening OVF source: foo.ovf

Warning: No manifest file

Opening VMX target: foo.vmx

Error:

- Line 2: Invalid value '1.0' for attribute 'version' on element 'Envelope'.

~/tmp]

This particular OVF was created with VirtualBox 2.2.4. Both support ovf 1.0, right? Output of line 2 ...

~/tmp] sed -n 2p foo.ovf

Ideas?
