Description of Problem:
Can't receive email from an account named "junk".

Steps to reproduce the problem:
1. Have 2 POP email accounts, me@x.com and junk@x.com
2. With Evolution 1.4, set up me@x.com to be the default mail account, and
junk@x.com to be another mail account.  Send and receive email, and
everything works.
3. Upgrade to Evolution 2.0.2.
  3a. Try to read your old junk@x.com mail
  3b. Try to receive new mail at junk@x.com

Actual Results:
3a. It has a new special "Junk" item instead of the junk@x.com account,
with an icon that looks like a blue sundial, and no messages in it.  There
seems to be no way to read my mail on this account.  (But note the file
~/.evolution/mail/local/Junk is the same size as the old
~/evolution/local/Junk/mbox, so it's probably just hidden, not deleted.)
3b. It shows an error: "Evolution Error" / "Error while Fetching Mail." /
"Cannot copy messages to the Junk folder." / "OK".

Expected Results:
My junk@x.com account should still work.

How often does this happen? 
Every time.

Additional Information:
My first thought was to change the name of the account, but its name (Tools
-> Settings -> Mail Accounts -> Edit -> Identity -> Name) is already
"junk@x.com", not "Junk".  So I don't know how to convince Evolution to put
it in a folder called something else (or what the "Name" field is good
for).  Also, the Defaults tab lets me pick where to put drafts and sent
messages, but not incoming messages.

It doesn't let me rename or delete the Junk item.
