/usr/share/doc/sysv-rc/README.policy-rc.d.gz says:

 invoke-rc.d built-in policy rules:

 To shield policy-rc.d of the underlying initscript system (file-rc, links in
 /etc/rc?.d or something else), invoke-rc.d implements the following built-in
 rules:

   1. action "start" out of runlevel is denied,
      (policy-rc.d receives action "(start)" instead of "start");
   2. action "restart" out of runlevel is denied,
      (policy-rc.d receives action "(restart)" instead of "restart");
   3. any action for a non-executable initscript is denied.

The reported behavior of invoke-rc.d is therefore inconsistent with the
package's own documentation because this was an out-of-runlevel start, and
furthermore, the documented behavior is reasonable whereas I don't believe
that the reported actual behavior is.

Or perhaps you misread the bug report and overlooked that this invoke-rc.d
invocation caused kdm to be started while in the system was in single-user
mode?
