Selecting Message -> New Message results in the composition window and immediately starts the external editor.  This is different from all previous releases.  I used to have to place the cursor into the edit area and hit any key to launch my editor.

Furthermore, the edit buffer I get omits my signature.  I have to type it in by hand.

If I save and exit my editor and then press a key in the composer area again, the full edit buffer, including my signature is loaded in my editor.

Reproducible: Always

Steps to Reproduce:
1.  Configure an external editor for the composer
2.  Either reply to a message or create a new message
3.
Actual Results:  
Composer window is displayed and the external editor is started immediately.  The editor's buffer does not contain the signature that appears in the composer window.

Expected Results:  
The composer window is started and the focus is in the headers.  I can complete the subject and headers and then move to the edit area and hit a key to start the external editor.  The external editor will contain my signature.
