1) I'm completely unfamiliar with git so I am not sure I understood this
one ... I had a look in the function testJensEftangBug(); all I was able
to conclude was that your asserts makes sense to me, but I probably
misunderstand something.
2) The output of EquationSystems::print_info() after initialization
(after adding the second system) is listed below. It looks sound to me.
3) DEBUG mode does not reveal anything new; it still just exits on the
libmesh_error().
(2) and (3) was with the git head
