            Bug ID: 430790
           Summary: Kontact crashes randomly at start
           Product: kontact
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: bugs at paclabs.nl
  Target Milestone: ---

Application: kontact (5.16.0 (20.12.0))

Qt Version: 5.15.2
Frameworks Version: 5.77.0
Operating System: Linux 5.9.14-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

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

Quite often when I start Kontact I receive a crash notification on my desktop.
In some cases there is no new window and I need to relaunch Kontact to use it
and in some cases Kontact window still show up after crash notification and I
can use it as normal. It seems like akkregator session is in all cases crashed
and needs to be restored or dismissed.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
