Description Stephan Diestelhorst 2017-05-05 10:34:16 UTC 
I am on KDE Neon with recent packages (below), and whenever I want to configure an existing IMAP account, the according akonadi IMAP instance dies with back trace attached.  I have tried to start with a clean Akonadi setup, but somehow my account data lives on.  Will try with a fresh user profile in a minute.

Backtrace:

Comment 1 Stephan Diestelhorst 2017-05-05 10:56:23 UTC 
Tried with a clean user profile, and it still crashes, see below.  Also pulled out newer package information and installed bebug symbols.  Will also have a look if it is related to bug #379089

After installing sasl2-bin and checking that the symlinks are correct, I still get the same / similar error (now with my old profile):

Comment 3 Christophe Marin 2017-05-05 15:19:15 UTC 
This happens with a GMail account, right ?
Comment 4 Stephan Diestelhorst 2017-05-07 22:38:36 UTC 
This is a little more complex than necessary.

The back traces ending in ServerTest::normalProtocols() are for my Office 365 work email account, but I have a separate GMail account in Akonadi.  The crashing imap agents are the O365 (non-GMail) ones, though.

The back trace ending in MailTransport::ServerTest::secureProtocols is one of an empty IMAP resource that I created after a half configured GMail account (which I deleted).  That empty IMAP resource I simply added in KMail and it would crash whenever I tried to configure it.

In both cases, the back traces are from an non-GMail resource, but there was a parallel (lingering) GMail account in both.

I will retry with a truly empty non-GMail account and not go through the wizard.
Comment 5 Stephan Diestelhorst 2017-05-07 22:53:27 UTC 
Okay, here is what I did:
* started with a fresh user account
* started KMail
* manually enter bogus account credentials for bogus server into wizard
* wizard complains (might not have a proper connection, please configure manually)
* attaching GDB (to the single imap agent)
* clicking configure
* crash -> backtrace
* closing KMail
* akonadictl restart
* and I get an _empty_ account (no server configured in akonadiconsole) and pretty much config file in ~/.config/../agent*imap*

I am on Archlinux , and I have the same issue, I can't add any IMAP account. 
I attach the backtrace of journalctl -f.

Comment 8 Sebastian 2017-05-14 16:00:26 UTC 
I am on openSUSE Tumbleweed (latest update), with KDE applications 17.04. I am facing the same issue. Once generated an IMAP resource in KDE's Kontact it can't be configured properly. The same happens using aconadiconsole (Agents --> IMAP resource --> Configure --> Configure Natively) - no window opens for configuration. The IMAP resource; however, is a standard Google mail account.

It has been backported and should be fixed in 17.04.2, see bug#379155.
