            Bug ID: 345076
           Summary: Crash while moving large folders
           Product: kmail2
           Version: 4.14.4
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: richard-oss at esplins.org

Application: kmail (4.14.4)
KDE Platform Version: 4.14.4
Qt Version: 4.8.6
Operating System: Linux 3.18.8-201.fc21.x86_64 x86_64
Distribution: "Fedora release 21 (Twenty One)"

-- Information about the crash:
- What I was doing when the application crashed:
I imported 100K mails from Thunderbird mbox files. I then tried to move those
folders from the depths of the Thunderbird import folder hierarchy to the root
of my Local Mail akonadi resource (KMail dir). It errored on one folder,
succeeded on one folder, and then crashed.

I am using KMail 4.14 on Fedora 21.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
