I tried to find the reason and failed. Documenting what I did in the 
hope that it helps in the future.

That's failing the third subtest of t/directive/perlloadmodule2.t.

Adding some debugging statements leads to:

Expected <dir: one two three four five six> but received <<!DOCTYPE HTML PUBLIC 
"-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>500 Internal Server Error</title>

Unfortunately the error log contains only:

 [perl:error] [pid 479:tid 140499903702784] [client 127.0.0.1:46172] Use of uninitialized value in string eq at /tmp/buildd/libapache2-mod-perl2-2.0.8+httpd24-r1449661/t/response/TestDirective/perlloadmodule2.pm line 85.

which is not very enlightening.
