GitLab

I have been trying to implement drag and drop support, so have needed to get the targets from Gtk.SelectionData. When ever I call get_targets, the program crashes with an error message like

(gjs:4288): Gjs-ERROR **: 09:05:06.317: Unable to resize vector

I have produced a small example that demonstrates this issue:

const Gtk   = imports.gi.Gtk;


const app = new Gtk.Application();
app.connect('startup', () => {
    const window = new Gtk.ApplicationWindow({ application: app, default_height: 325, default_width: 720});

    const entry = new Gtk.Entry();

    entry.connect('drag-data-received', (entry, context, x, y, data) => {
        data.get_targets();
    });

    window.add(entry);
    window.show_all();
});

app.run([]);

Dragging and dropping a file onto the chat entry gives the error message. I am running Gjs 1.52.1
