Attachments: Akonadi_imap_resource crashes from time to time

Description Aaron J. Seigo 2014-08-09 19:49:42 UTC 
Occasionally the IMAP resource crashes on my system using the openSuse packages.

I have not yet noticed a reliable pattern, though it *might* be related to / triggered by network going away / becoming available again. I have not confirmed this sufficiently, however, so that may be a red herring. (Sorry..)

The IMAP resource was set up by the Kolab account wizard and there are a number of folders that are tracked (mail, calendars, ..) as can be seen by the # of threads.

Application: imap.mykolab.com of type IMAP E-Mail Server (akonadi_imap_resource), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Akonadi_imap_resource crashes from time to time
Comment 2 Denis Kurz 2016-09-24 20:44:26 UTC 
This bug has only been reported for versions older than KDEPIM 4.14 (at most akonadi-1.3). Can anyone tell if this bug still present?

If noone confirms this bug for a recent version of akonadi (part of KDE Applications 15.08 or later), it gets closed in about three months.
Comment 3 Denis Kurz 2017-01-07 21:29:43 UTC 
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
