I'd love to see a 'bt full' on this one.

Ditto, bt full.

This one may need valgrind to track down the problem, but please be sure
to run 1.4.18 or later, as we've already fixed a problem that produced
backtraces similar to this.

I don't see anywhere on that page that recommends that you try SVN trunk,
only the latest SVN (which is probably confusing, but what is meant is to try
the latest SVN in the 1.4 branch, which is the release branch.  Release
candidates and releases are tagged directly off that branch).
