ipc/tests/ipctest.js and tests/tests/ipc.js

Indeed I think you do :-) I imagine that you use a recent nightly build
of Enigmail -- but if you check the latest ipc tar file
(http://mozilla-enigmail.org/ipc/ipc-latest.tar.gz), you'll see that the
1st parameter has changed, it's now an nsIFile. I.e.

it should be:
var dummyFile =
Components.classes["@mozilla.org/file/local;1"].createInstance(Components.interfaces.nsILocalFile);
dummyFile.initWithPath("C:\\Dummy.exe");
dummyFile = localfile.QueryInterface(Components.interfaces.nsIFile);

pipeTransport.init(dummyFile,
                   aArguments, aArguments.length,
                   [], [].length,
                   0, "", true, true, null);

You can actually build ipc separately from Enigmail, just unpack the tar
 file to .../mozilla/extensions, and build it just like you'd build
Enigmail.

I currently don't create regularly builds of ipc. The difficulty is that
Thunderbird and SeaMonkey need to be compiled differently than Firefox,
XulRunner etc, and I just can't create 8 variants of ipc builds in
addition to the 4 variants of Enigmail that I already build.
