Public bug reported: Binary package hint: notification-daemon
themes/ubuntu/theme.c: static gboolean mouse_over(GtkWidget *win, GdkEventExpose *event, WindowData *windata) { gtk_widget_set_state((WindowData*)windata->close_button, GTK_STATE_PRELIGHT); } static gboolean mouse_over_end(GtkWidget *win, GdkEventExpose *event, WindowData *windata) { gtk_widget_set_state((WindowData*)windata->close_button, GTK_STATE_NORMAL); } These need to return FALSE not some undefined value! I also noted that you can replace #define M_PI 3.14159265358979323846 with just using glib's G_PI (and G_PI_2). ** Affects: notification-daemon (Ubuntu) Severity: Normal Priority: (none set) Status: Unconfirmed -- bugs in 'ubuntu' notification theme https://launchpad.net/bugs/44908 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
