How to Reproduce

While doing a GET operation on /browser, Trac issued an internal error.

I clicked the button "Browse Source" and this error occurred.

It seems that, as my experience, currently, the only solution for subversion 1.4.4 and apache httpd-2.2.3 is to use the apr-1.2.7 inside httpd-2.2.3 instead of the apr-0.9.4 inside subversion-1.4.4 (as well as apr-util). By using the same apr & apr-util from httpd, this issue could be fixed.
