Doh. May need to get the children of these before this happens. (I
forget that varobj inserts the protection level as a child.)

Could be. I would try fetching the children of "var1.protected",
"var1.private", and "var1.public" in MI. If it crashes or complains,
it's really a core problem.

Try getting those children, and we'll see where it goes.
