            Bug ID: 368837
           Summary: kmail crash when expiring messages in a folder
           Product: kontact
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs@kde.org
          Reporter: jama...@fep.up.pt

Application: kontact (5.3.0 (QtWebEngine))

Qt Version: 5.7.0
Frameworks Version: 5.26.0
Operating System: Linux 4.8.0-0.rc5.git1.1.fc25.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
I have a gmail account where I receive several mailing lists.

Since those mailing lists are archived elsewhere there is no need to have them
archived and at the same time kmail gets slow when reading huge folders.

So I have decided to expire messages. In some cases like this mail has crashed
while expiring the folders initially.

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