Segfault in libsvn_subr.so.1 - subversion-1.3.2

I am receiving the following error whenever I use an SVN client to
access a repos via apache2 (mod_dav + svn.

/var/log/apache2/error_log:

I am using the following Gentoo packages:
apache-2.0.58-r2
mod_dav-1.0.3-r3
subversion-1.3.2-r3
I have so far been unable to get debugging symbols built in subversion 
so that I might debug this. I did try passing configure 
--enable-maintainer-mode, but gdb still did not locate symbols...
Any hints where to go from here?
Thanks.
