Extension crashes with indicator.get_parent() is null

[twalkerA]

Hello Andia89,

Within the last two weeks the extension has been crashing. It seems to happen after I unlock my screen. The error in Extension Manager is "indicator.get_parent() is null"

I am using Ubuntu 22.04lts.

Thanks for creating this extension. And, thank you for looking into this issue.

It happens to me too on Fedora 40 with Gnome 46.
Some log from journalctl of it can help.

gnome-shell[6145]: Object St.Bin (0x561357ff5810), has been already disposed — impossible to access it. This might be caused by the object having been destroyed from C code using something such as destroy(), dispose(), or remove() vfuncs.

Same problem for me. Same error message. My gnome-shell crashes once a day due to this problem.
Gnome 46, Ubuntu 24.04.

I tried the following patch.
In extension.js, replace:

        let box = indicator.get_parent().get_parent();
        if (box == undefined) continue
        this._addToPanelBox(role, indicator, 0, box)

With:

 if (indicator.get_parent() != null)
        {        
            let box = indicator.get_parent().get_parent();
            if (box == undefined) continue
            this._addToPanelBox(role, indicator, 0, box)
        }

I got no crash since.
