Problems with updated, but long used versions of Evolution

[Dr. John H. Lauterbach]

Please see information below that I sent to the experts on Evolution.  On two
installations of Evolution (both the ones for 18.04 and 18.10), addition of a
second IMAP email account, causes Evolution to "lock up".  For example, use of
  CAMEL_DEBUG=imapx:io evolution give the following when a second IMAP account
is enabled:

> [imapx:A] I/O: 'A00103 LOGIN ...'
> [imapx:A] I/O: 'A00103 NO [AUTHENTICATIONFAILED] Authentication failed.'



As soon as the second IMAP account is disabled, the problems goes away.

Thank you, John

Removing and reinstalling Evolution is probably pointless, all the more
so as you say the same problem occurs on two different machines. Linux
isn't Windows. You're just restoring all the Evolution components to
what they were before you removed them. You can also verify the package
installation. On Fedora this would be "rpm -V <package-name>". On
Ubuntu I assume there's something similar. That would check that there
isn't bit-rot in the installed components, but frankly the likelihood
of this manifesting as anything other than a crash is infinitesimal.

Before doing all this however, check the number of concurrent
connections to the mail server, under <account>->Receiving Options. See
if it's different between the machines that work and those that don't.

If all else fails, by all means try recreating the accounts. There may
be some configuration error.
