For some reason the Google Mail web client detects patches with .patch
extension as application/mbox now. If I rename it to .diff, it's
correctly detected as text/x-diff. There seems to be no way to
explicitly tell the client which mime-type an attachment should have.
Anyway, here is another patch for a similar leak in xenDaemonLookupByUUID().
