Bug 361608

Application: akonadi_imap_resource (4.89.0)

Qt Version: 5.5.1
Operating System: Linux 4.2.0-35-generic x86_64
Distribution: Ubuntu 15.10

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

I was syncing kmail with my work place's exchange server through IMAP via Davmail.
Note: This happend during an initial sync covering two years worth of emails.

May be related to bug: 353957 (the stack trace is awfully similar). Although the crash reporting assistant wouldn't let me link my bug report to this one.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Akonadi Resource (akonadi_imap_resource), signal: Segmentation fault
