A USB filter is stored in a hostdev. The original code doesn't allocate hostdev->info that is expected to be allocated with hostdev. So use virDomainHostdevDefAlloc() to allocate both as we expect.

ACK on this fix, which I pushed. But just taking a quick look at that small chunk of the gigantic function it's part of (vboxDomainGetXMLDesc), I saw two other problems that need fixing. Since you seem to have an interest in a properly working vbox driver, you might want to look into making patches to: 1) properly handle out of memory errors (and other errors - there is absolutely no error handling in that function). 2) Fix this apparently incorrect comparison just above the current patch: for (i = 0; (USBFilterCount < def->nhostdevs) || (i < deviceFilters.count); i++) { (I'm pretty sure that "||" needs to be "&&", but don't want to patch code that I can't test).
