sounds like it should be fixed by this commit:

https://svn.apache.org/viewvc?view=revision&revision=r1711479

"Fix crash in ap_mpm_pod_check call caused by NULL dereference of its 
parameter when starting httpd as single process (httpd -X)."

The crash is easily reproduced on the command line with:

apache2ctl stop
apache2ctl -X

# different shell
curl http://localhost/
