            Bug ID: 324233
           Summary: crash while starting migration to kmail2, after
                    certificate warnings
    Classification: Unclassified
           Product: Akonadi
           Version: 4.10
          Platform: Debian testing
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: IMAP resource
          Assignee: ervin at kde.org
          Reporter: wankelwankel at yahoo.com
                CC: kdepim-bugs at kde.org, vkrause at kde.org

Application: akonadi_imap_resource (4.10)
KDE Platform Version: 4.10.5
Qt Version: 4.8.5
Operating System: Linux 3.10-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (jessie)

-- Information about the crash:
- What I was doing when the application crashed:
I just started migrating from kmail to kmail2. There were many popups asking
for access to kdewallet and warnings about certificates (two accounts tend to
give a warning, and it seems many threads were opened at the same time)
So far, there was a crash especially for one account, it seems the rest of
kmail2/migration daemen is not informed of the crash yet.

- Unusual behavior I noticed:
There were really a lot of connections opened all at once (no logging, just
feeling so, since there were numerous popups asking acces to kwallet and giving
warnings about the certificate)

-- Backtrace:
Application: b at osba of type IMAP E-Mail Server (akonadi_imap_resource), signal:
Segmentation fault
