            Bug ID: 378314
           Summary: Akregator closes every time without any (apparent)
                    reason after some time loading feeds
           Product: akregator
           Version: 5.4.3
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: xnake at openaliasbox.org
  Target Milestone: ---

Application: akregator (5.4.3)

Qt Version: 5.7.1
Frameworks Version: 5.32.0
Operating System: Linux 4.10.4-1-default x86_64
Distribution: "openSUSE Tumbleweed"

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

I use to close Akregator every time I turn off PC because I don't know if the
bug that makes it not to remember read/unread messages is fixed, and (maybe)
three days ago it closes unexpectedly when loading feeds. After first crash it
always show a message saying if I want to restore to previous state and I say
Yes. After some time, Akregator crashes again and shows the send report/restart
app dialog

The crash can be reproduced every time.

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