Segmentation fault when starting Apache, if mod_dav_svn.so is loaded

Hi,

I have upgraded my Linux version from Fedora4 to Ferdora5, and now the
Apache server doesn't start anymore. While starting, there is a
Segmentation fault that appears, and the starting fails. If I just
remove the mod_dav_svn.so module from Apache .conf file, the Apache
server starts without any problem.

I remember that I was using the Apache version 1.xx before the new
upgrade, but now it is 2.2.0, with the same version of subversion
(1.3.2, the latest one).

I have tried to do some debug and I have found the following(when the
problem occurs)

Program received signal SIGSEGV, Segmentation fault.
