Can't install any appliance

[karavan]

I seem to be unable to install any virtual appliance in VirtualBox right now. I've tried uninstalling and reinstalling VirtualBox, and have deleted and re-downloaded the VMs, but am having no luck. Each one gives me a different error, but they all seem to be pointing me to a .cpp file, which I cannot seem to locate, and if I did, I wouldn't know what to change.

These are VMs that worked fine on my previous machine with an earlier version of VirtualBox. These are fairly widely distributed machines, and I cannot find anyone else that has these problems, so I'm wondering if it's something local to my machine or VirtualBox install. Any ideas would be very welcome.

Details as follows:

Host machine: Mac OS X 10.8.3

VirtualBox: 4.2.12 with extension pack installed

The error message seems clear - the ovf file is corrupted. Glancing at at with a suitable text editor should prove if it's a valid XML.
