[Bug 578681] [NEW] apache2 crashes on svn query with kerberos + ssl

[Sönke von Heymann]

Public bug reported:

Binary package hint: apache2

Description:    Ubuntu 10.04 LTS Server
Release:        10.04
apache2         2.2.14-5ubuntu8

Hudson queries svn-server for a repository, the connection drops and apache crahes.
svn-queries using tortoise-svn work perfectly

The svn-server is the only site running on that server.
