Looks like garbage to me.  This value comes from here:

  lisp_selection
    = x_get_local_selection (selection_symbol, target_symbol,
                             0, dpyinfo);
  ...
  lisp_data_to_selection_data (SELECTION_EVENT_DISPLAY (event),
                               lisp_selection,
                               &(cs->data), &(cs->type),
                               &(cs->size), &(cs->format),
                               &(cs->nofree));

The commentary to x_get_local_selection says:

  /* Given a selection-name and desired type, look up our local copy of
     the selection value and convert it to the type.
     The value is nil or a string.

So we need to receive a string, not an integer.

Could you please go up one stack frame, to frame #3, and show the
value of lisp_selection (with the same "pp" command)?

Jan, feel free to chime in, as I'm already on unfamiliar turf.  I
smell a Synergy bug, but only an expert can tell for sure.
