            Bug ID: 380991
           Summary: Crash due to "ambiguous shortcut"
           Product: konsole
           Version: 16.04.3
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: seon.wook at swook.net
  Target Milestone: ---

Since the last set of updates to my Ubuntu 16.10 installation (which did not
include konsole), I can no longer start konsole.

I get a window with title "Ambiguous Shortcuts" then a crash. This occurs 100%
of the time. I tried moving ~/.local/share/konsole to no effect.

Thanks in advance for looking into this.

Crash report follows:
---

Application: konsole (16.04.3)

Qt Version: 5.6.1
Frameworks Version: 5.34.0
Operating System: Linux 4.8.0-53-generic x86_64
Distribution: Ubuntu 16.10

-- Information about the crash:
<In detail, tell us what you were doing  when the application crashed.>

The crash can be reproduced every time.

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