I'm sorry that I don't have full debug information, but hopefully this will
give a clue as to where this may be crashing. I have spent a few minutes
trying to track it down, but have not been successful up to this point. I can
try testing this problem with the current subversion HEAD, but I need to be
able to maintain binary compatibility with 2.6.0, so a small patch would be
most welcome. It's worth noting that no errors are reported when running this
in 2.3.0. We do not have an installation of 2.4.0 or 2.5.0 to test with.
Thanks.
