            Bug ID: 405243
           Summary: Akregator crashes when trying to close tab which is
                    trying to load a video
           Product: akregator
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: DonaldEdwardWinslow at gmail.com
  Target Milestone: ---

Application: akregator (5.9.3)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.20.5-200.fc29.x86_64 x86_64
Distribution: "Fedora release 29 (Twenty Nine)"

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

I tried to close a tab with a video that would not load.

- Unusual behavior I noticed:

Akregator crashed earlier for a different reason. It's taking a long time to
load feeds.

The crash can be reproduced every time.

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