Unfortunately, you seem to have found the same bug I uncovered in March:
http://mail-archives.apache.org/mod_mbox/apr-dev/201003.mbox/%3cb51ffb6f1003100926n22c1dd79id9696972b23a1...@mail.gmail.com%3e
To my knowledge it hasn't been fixed, thought that thread does include
a somewhat hacky patch to work around the issue. Perhaps it will be
of use to you.
