1. Open a new compose window by clicking the Compose button in the toolbar.
2. Then click Help > Migration wizard.
3. You find out that there's a blank window opening, as opposed to when the migration wizard is opened using the Main window.
NB: I'm sorry for all the German in the screencast :P

From what I can see aParentWin references the open Compose Mail window, not the Thunderbird main window. In the TB main window, there's a gFolderTreeView, but not in the Compose mail window. That's why that check fails. Maybe I can fix it myself.
You can probably do something like this in fc_init - http://mxr.mozilla.org/comm-central/source/mail/base/content/featureConfigurator.js#102
aParentWin = Services.wm.getMostRecentWindow("mail:3pane");
However... with no 3pane open things will get more complicated.
Did i hear there were plans to get rid of the migration wiz, btw? Blake?
Yeah, I think there are plans, but we haven't gotten around to it yet.
Ok, let's hijack this bug for the removal.

Almost seems like a shame, but i think it's played it's role.

Yep, looks good to me, although I'll be a little sad to see it go… :) ui-r=me, r=me.

I've landed a build bustage fix for this - http://hg.mozilla.org/comm-central/rev/499441818d84
Note that there's also some mozmill cruft that seems left over - http://mxr.mozilla.org/comm-central/source/mail/test/mozmill/shared-modules/test-window-helpers.js#1257

thx for the patch, r=me; it would be nice if you restore the comma after the next to last } so that if anyone adds something to that code, they won't get bit by the missing ','.
