It does,... but there is no LoadModule directive in the respective
config files; just the config snippets for the handler assignments and
some comments, as I've said before.
(We're still talking about php5-cgi's php5-cgi.conf/.load files, are

Yeah,... well... to be honest I don't think there's an automatic "fix"
to get everything working as it was.
We should add another bunch of notes to the release files, that the
SetHandler definitions from php5-cgi's config snippets may override
other Handler definitions.

But as I said, Apache configs may be just way to complex to handle this
all out of the box; at least I don't see a way currently.

Perhaps one should also add note, that these "fake" module config files
are added and that admins are expected to have a look at it.

At least I don't see a way to take these "fake" module config files as
this would not only break sites, but also cause security issues (php
files being exposed).

Questions for those who are affected by this bug:
1) So you have both, php5-cgi AND libapache2-mod-fcgid installed, right?
2) Then what happens is, the Handler from php5_cgi.conf overrides the
way (whatever you did) to get .php files interpreted, right?
3) Obviously, .php files are then neither interpreted by "normal" CGI,
as Action directives are missing (and perhaps ScriptAlias and other
things), right?

So we definitely get broken services (which by itself may cause security
issues - but no one could really ever cannot cover these kinds of
Big problem though is, are the files then served as normal files by
