crash when starting the panel

[dkondor]

Hi,

I'm trying to test the GTK4 version of the panel, but get the following crash:

The call at src/panel/widgets/window-list/toplevel.cpp:459 that causes the crash is the following:

minimize_action->set_state(Glib::wrap(g_variant_new_boolean(false)));

However, this seems to be a null reference:

(gdb) print minimize_action
$2 = std::shared_ptr<Gio::SimpleAction> (empty) = {get() = 0x0}

Which is weird given that minimize_action is set in the constructor (line 85). Maybe the problem is that the listener is added before this? (line 58)

I'm using the latest master (6920bbe) on Arch Linux with a recent version of Wayfire (0.11)
