This looks like the bug that is being discussed in another thread. John
Fleck just filed this bug report:

        http://bugzilla.gnome.org/show_bug.cgi?id=125653

and your investigations seem to point to the same thing.

I should point out that with scrollkeeper it is a bit more tricky
identifying the exact problem, since there were a number of memory
management problems in scrollkeeper that have been fixed recently. If
you are building from the 0.3.12 tarball, then you may be able to
trigger some of those (I never could, but they existed in theory).
However, in this case, I think you are looking at a libxml bug.
