Bug 361101

Application: akonadi_imap_resource (4.14)
KDE Platform Version: 4.14.2 (Compiled from sources)
Qt Version: 4.8.6
Operating System: Linux 3.19.0-32-generic x86_64
Distribution: Linux Mint 17.3 Rosa

-- Information about the crash:
- Unusual behavior I noticed:
I have serveral IMAP accounts, 2 of them with Hotmail, and this one in particular takes a long time to load new email. Sometimes, after coming from hybernation, the email does not respond anymore. Shutting down the application and re-opening it is not enough. I am forced to restart the computer.

Prior to this happening, I had come back from hybernation (Kmail had been closed) and I received repeated messages that Akonadi was unable to delete events in the calendar. I was forced to restart the computer as no application was responding. Upon restarting, I opened Kmail and the problem described with the IMAP acocunt happened.

The behaviour described with the Calendar deletion has happened several times in the past.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Casa Infinito of type IMAP E-Mail Server (akonadi_imap_resource), signal: Segmentation fault
