CEDET

Yes, C-c . is a popular prefix key for both EDE, and a few other random 
minor modes.  There just aren't enough prefixes out there. ;)

>From the Elisp Manual, (sec. D.2: Key Binding Conventions):

   * Sequences consisting of `C-c' followed by `{', `}', `<', `>', `:'
     or `;' are also reserved for major modes.

   * Sequences consisting of `C-c' followed by any other punctuation
     character are allocated for minor modes.  Using them in a major
     mode is not absolutely prohibited, but if you do that, the major
     mode binding may be shadowed from time to time by minor modes.

IIUC (and Eric's reply seems to confirm that), CEDET binds `C-c .' in
a minor mode, whereas Org is a major mode. So if anything, you should
be complaining on the Org list instead ;-).
