Description bojko_1000 2014-04-17 12:56:31 UTC 
Code @566:
            if (data->xwindow) {
                Atom _net_frame_extents = X11_XInternAtom(display, "_NET_FRAME_EXTENTS", 0);
                Atom type = None;
                int format;
                unsigned long nitems = 0, bytes_after;
                unsigned char *property;
                X11_XGetWindowProperty(display, data->xwindow,
                    _net_frame_extents, 0, 16, 0,
                    XA_CARDINAL, &type, &format,
                    &nitems, &bytes_after, &property);

                if (type != None && nitems == 4)
                {
                    border_left = ((long*)property)[0];
                    border_right = ((long*)property)[1];
                    border_top = ((long*)property)[2];
                    border_bottom = ((long*)property)[3];
                }
            }

Code after _the fix_:
            if (data->xwindow) {
                Atom _net_frame_extents = X11_XInternAtom(display, "_NET_FRAME_EXTENTS", 0);
                Atom type = None;
                int format;
                unsigned long nitems = 0, bytes_after;
                unsigned char *property;
                X11_XGetWindowProperty(display, data->xwindow,
                    _net_frame_extents, 0, 16, 0,
                    XA_CARDINAL, &type, &format,
                    &nitems, &bytes_after, &property);

                if (type != None && nitems == 4)
                {
                    border_left = ((long*)property)[0];
                    border_right = ((long*)property)[1];
                    border_top = ((long*)property)[2];
                    border_bottom = ((long*)property)[3];
                }
                X11_XFree(property);
            }

I have found that leak with valgrind.
