Lisp error while using ede-cpp-root-project

I've been trying to get the CEDET working with a simple project for the last little while. I have the following project file:

(ede-cpp-root-project "aesalon-project"
                :name "aesalon-name"
                :file "~/projects/aesalon/SConstruct"
                :include-path '("/"
                                "/include/"))

I've been loading the above into a buffer and executing the buffer contents. The problem is not with the project not loading correctly -- it seems to bet set up properly; I can change the settings etc. using the menubar. When I try to rescan the project's files, however, I get the following error:

Debugger entered--Lisp error: (wrong-type-argument class-p ede-cpp-root)
  signal(wrong-type-argument (class-p ede-cpp-root))
  child-of-class-p(ede-cpp-root-project ede-cpp-root)
  object-of-class-p([object ede-cpp-root-project "aesalon-project" nil "aesalon-name" "1.0" "/home/ethereal/projects/aesalon/" 3546321 "/home/ethereal/projects/aesalon/SConstruct" nil nil nil unbound unbound "" "" "" "" "" "" ("debug" "release") "debug" nil ("/" "/include/") nil nil nil "\\.\\(h\\(h\\|xx\\|pp\\|\\+\\+\\)?\\|H\\)$\\|\\<\\w+$" nil] ede-cpp-root)
  ede-toplevel-project("~/projects/aesalon/")
  ede-rescan-toplevel()
  call-interactively(ede-rescan-toplevel nil nil)

I find this somewhat odd, as when I look at the documentation for ede-cpp-root-project I see that it has ede-project as its parent, not ede-cpp-root? Or am I misunderstanding the trace? I'm not very familiar with Emacs Lisp.

Here's my output from cedet-version:

C-h f cedet-version RET

And my emacs version: (latest from Arch Linux repositories)

GNU Emacs 23.4.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.24.9) of 2012-02-01 on shirley.hoetzel.info

Does anyone have any suggestions on how I could go about fixing this issue? Is it a problem with my project? My CEDET environment? Version of emacs?

Solution

Apparently the problem is inconsistencies in EDE and CEDET. As best I can tell, the version of the CEDET that I was using was relying on an old architecture of EDE that has since been changed.

Compiling the CEDET from the latest source tree instead of the (older) snapshot I was using fixed the problem.
