Description of problem:
I have two Gmail accounts, and sometimes I want to send mail from Evolution
using those accounts. Not wanting to download hundreds of MBs of mail via POP3,
I set the Receiving server type to None.

With evolution-2.3.7 this works fine; with 2.3.8 though, trying to edit the
accounts with Protocol=none crashes Evolution.

Version-Release number of selected component (if applicable):
2.3.8-3

How reproducible:
Always

Steps to Reproduce:
1. Set up an account without a Receive: server (server type set to None)
Might need to do it using Evo 2.3.7
2. Edit the account
3.
  
Actual results:
Evolution crashes (output log below)

Expected results:
The account should be editable like other accounts
