            Bug ID: 427411
           Summary: Kontact crashes on Sending Mail
           Product: kmail2
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: anca.tibor at posteo.de
  Target Milestone: ---

Application: kmail (5.15.1 (20.08.1))

Qt Version: 5.15.1
Frameworks Version: 5.74.0
Operating System: Linux 5.8.12-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

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

I submitted a document from LibreOffice Writer to Kmail/ Kontact. Hitting Send
Mial caused a complete crash of Kontact (I could reproduce it). On restart
Kontact opened the E-Mail, there was no data loss. Very annoying behaviour,
however.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
