The fix for Zenity bug 670496 "Zenity info/error windows grow in height with message length" (https://bugzilla.gnome.org/show_bug.cgi?id=670496) stopped working on recent Gtk, which doesn't seem to honor gtk_widget_set_size_request. This commit workarounds Gtk bug 657621 "Calculate the wrong height of labels wrapping on words" (https://bugzilla.gnome.org/show_bug.cgi?id=657621) by setting label's width-chars and max-width-chars to 60. This magic number was picked from GtkMessageDialog source (https://git.gnome.org/browse/gtk+/tree/gtk/ui/gtkmessagedialog.ui#n48).
