            Bug ID: 374667
           Summary: Crash opening akregator from kontact
           Product: kontact
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: rjwgnr27 at yahoo.com
  Target Milestone: ---

Application: kontact (5.3.3 (QtWebEngine))

Qt Version: 5.6.2
Frameworks Version: 5.27.0
Operating System: Linux 4.8.15-200.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"

-- Information about the crash:
New upgrade to Fedora 24. When I start kontact (kontact-16.08.3-2.fc24.x86_64,
akregator-16.08.3-2.fc24.x86_64), then switching to my feeds, I am told that
"Akregator did not close correctly. Would you like to restore the previous
session?".  Selecting either "Restore Session" or "Do Not Restore Session"
causes this crash. I have not tried "Ask me later".

The crash can be reproduced every time.

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