Please describe the problem:
I built 2.21.5 from SVN this morning.  After that, when I try Send/Receive mail, Evo pops up a dialog asking for my password for my POP (APOP) account.  I enter it, then the send/receive dialog goes away immediately.  No error dialog is shown, and no mail is downloaded (if I go to the server separately I can see that my account still has mail in it).

If I click Send/Receive mail again, I get the same behavior over again and still no mail is downloaded.

Steps to reproduce:
1. Create a POP account
2. Click Send/Receive mail
3. Enter password


Actual results:
No mail is downloaded.

Expected results:
Mail is downloaded.

Does this happen every time?
Yes.

Other information:
I have debugging enabled, and this is what I see:

Note I did NOT, of course, cancel the operation myself.
