            Bug ID: 371769
           Summary: konqueror crashes on Wayland with an empty clipboard
           Product: konqueror
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konq-bugs@kde.org
          Reporter: monkeyboyted@yahoo.com
  Target Milestone: ---

Application: konqueror ()

Qt Version: 5.7.0
Frameworks Version: 5.28.0
Operating System: Linux 4.4.0-270-bb x86_64
Distribution: KDE neon Developer Edition

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

I was clearing the clipboard on kde wayland.

Another time I was restorting a kde session with konqueror as on of the
windows.


Steps to reproduce:
1. start plasma-wayland
2. clear kde clipboard.
3. start up konqueror.

Added bonus.

1. enable restore previous session in systemconfig -> kde startup
2. konqueror
3. shutdown
4. boot up plasma-wayland
5. Konquerors crashes regardless if clipboard is full or empty.

- Unusual behavior I noticed:

The only reason why I notice bug 346346 is because dr konqi reference the bug
when it crashed on start up.





I appoligize for a seperate bug post but dr konqi "suggest bugs might be
related is broken"

This issue seems to be reported ages ago - Bug 346346 

I am using

kde neon developer edition

The crash can be reproduced every time.
