This may or may not be related, but on my system, Apache starts
successfully but the Apache error log is filled with:

On the debian-apache mailinglist i found a post saying that the real
error is in libapr0. You can downgrade apache2-common,
apache2-mpm-prefork and libapr0 to 2.0.50-8.

I've tried this and now my apache2 with php4 and svn work again.

post-warty version

Subject: apache2: another report

Package: apache2
Version: 2.0.50-9
Followup-For: Bug #266279

I experience problems, too.
Apache works for me after removing the php4-module (active modules now:
cache cgi encoding mime_magic mod-security perl rewrite ssl userdir).
If I enable php4-support, some things still work
(http://patric.members.selfnet.de/bilder/ is created by mod_gallery, an
apache modules), but others (sending php-sites or static html-pages) are
broken.
The server itself runs fine at any time, the child-processes die with a
segfault.

I hope I could help you to fix this bug.

These bugs were fixed in NMUs by me which are, apparently, no longer
considered NMUs because I'm now part of the apache2 maintenance team.
