I see this on history test 1 (among others) when running davautocheck
and compiled with the shims enabled. It happens run running 'svn up
-r1' when the working copy is at r2, and r2 had a file replacement.

I might have been wrong about which bit of ra_neon was driving the
delete_entry() handler. I'll double check that bit later this
