Application: akonadi_imap_resource (4.14)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.17.4-031704-generic x86_64
Distribution: Ubuntu 14.04.1 LTS

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

Left GMail IMAP resource running over night and this morning the thing crashed.  Restarting the agent does scanning of some folders, and then crashes with this bug reproducibly within tens of seconds.

Happy to add more detial, will akonadictl restart next.

The crash can be reproduced every time.

-- Backtrace:
Application: GMail vom Typ IMAP-E-Mail-Server (akonadi_imap_resource), signal: Segmentation fault

It really seems to be a dupe of bug 341860 , and bug 340157 looks quite similar, too.

New crash information added by DrKonqi

akonadi_imap_resource (4.14) on KDE Platform 4.14.5 using Qt 4.8.6

- What I was doing when the application crashed: watching a movie, listenning to music, or nothing at all.

I receive this error every 5 or 10 minutes, whatever the thing I am doing.

This error makes kmail unusable for me: either I leave the error opened and I cannot check for new emails, or I close it and it is going to reappear soon.

-- Backtrace (Reduced):

Looks like bug #345748 is a duplicate and my bug #351515 could be the current state of the same bug. I don't know the code, but from the backtrace they both seem to trigger after receiving something. I know this is a hand-waving argument.

I  am getting this crash too  I am on arch

here is the backtrace
