Product: [Applications] akregator Reporter: Ivo Vinicius <ivoviniciusspjsl>
Component: generalAssignee: kdepim bugs <kdepim-bugs>
Status: RESOLVED DUPLICATE

Sentry Crash Report:

Description Ivo Vinicius 2018-03-05 23:20:04 UTC 
Application: akregator (5.5.3)

Qt Version: 5.9.1
Frameworks Version: 5.43.0
Operating System: Linux 4.13.0-36-generic x86_64
Distribution: Ubuntu 17.10

-- Information about the crash:
- What I was doing when the application crashed:
every time i attempt to run akregator, it crashes before opening any window, only a notifications says segmentation fail (11).
- Unusual behavior I noticed:
 if i try to open akregator inside the kontact application, it works just fine.
- Custom settings of the application:
i made an attempt to remove kontact of my computer, since then akregator does not work, although it is installed, i have installed kontack back.

The crash can be reproduced every time.

-- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
