-- Information about the crash:
- What I was doing when the application crashed:

GMail was asking for SMTP password and because of that a password input window was shown. Some seconds later, the agent crashed after it had shown that the remote machine closed the connection.

Git commit 14894befa0274e124cdde611dfb7ada8b1131b07 by Ahmad Samir.

SmtpJob: Fix crash in startLoginJob

- The user tries to connect to an smtp server, the password dialog is shown
  starting a nested eventloop with exec()
- the connection is lost, the smtpjob is killed (due to connect() in startSmtpJob)
- the dialog::exec returns, and the code tries to setError(KilledJobError)
  on an already killed job which leads to a crash

fix the issue by using QDialog::open() to make the code async.
