            Bug ID: 415109
           Summary: Latte Dock crash when opening settings
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: mikesht10 at gmail.com
  Target Milestone: ---

Application: latte-dock (0.9.3)

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-24-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- Unusual behavior I noticed:
The dock froze and crashed when displaying the settings panel. Relaunching the
app is impossible without a restart, after one - the crash repeats

The crash can be reproduced every time.

-- Backtrace:
Application: Latte Dock (latte-dock), signal: Bus error
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
