What did you mean by "don't handle" here?  The following entry

  040000 tree 22d5826c087c4b9dcc72e2131c2cfb061403f7eb	empty

should be not a problem; empty tree is hardcoded and also shouldn't there
be a problem with such object.  Is the problem when checking out such tree
(writing to index and/or working area)?

Well, then 1.8.0 version could be good place to break backwards 
compatibility; we did similar thing when introducing submodule entries,
isn't it?
