akonadi_ews_resource is crashing today.

[Andy Wood <ayup.gromit@gmail.com>]

After working for many years, today I cannot re-authenticate to a Corporate 
O365 system.  The pop-up that normally prompts for password and OTP crashes.

Up to date Debian forky system.

Don't really know how to debug this, but tried:
/usr/bin/akonadi_ews_resource --identifier akonadi_ews_resource_4

and the final message is:
KCrash: Application 'akonadi_ews_resource' crashing... crashRecursionCounter = 
2
Segmentation fault  (core dumped).

Is this part of kdepim-addons?

Andy.
