            Bug ID: 358586
           Summary: akregator crash after startup (after system crash)
           Product: akregator
           Version: unspecified
          Platform: Gentoo Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: mschiff at gentoo.org

Application: akregator (5.1.2)

Qt Version: 5.5.1
Operating System: Linux 4.1.6-gentoo x86_64
Distribution: "Gentoo Base System release 2.2"

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

My Laptop went out of battery, so I had to restart. Akregator asks to restore
session, I choose "YES", then click on some feed in the feedlist. Before the
list appears: kaboom!

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