Bug 441054

Application: latte-dock (0.10.0)

Qt Version: 5.15.3
Frameworks Version: 5.84.0
Operating System: Linux 5.11.0-7620-generic x86_64
Windowing System: X11
Drkonqi Version: 5.22.4
Distribution: KDE neon User Edition 5.22

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

Plasma startup.

- Custom settings of the application:

The Active Window Control plasma applet is set to hide window titlebar when maximized. I suspect this may be related directly to the crash,  I have to go and enable the setting each time plasma is loaded. This started at the same time that Latte dock crashes on startup.

If I manually enable the "hide titlebars when maximized" setting and lauch Latte dock after startup, everything seems to work fine.

The crash can be reproduced every time.

-- Backtrace:
Application: Latte Dock (latte-dock), signal: Segmentation fault
