AFAIK the daemon has no frame. The user must create one. I do that with
`emacsclient -c -n'.

Indeed, the function is counting two visible frames:

Breakpoint 1, other_visible_frames (f=0xf43590) at /home/oscar/dev/emacs/emacs/src/frame.c:1120
1120    {
(gdb) n
1123      if (f == SELECTED_FRAME ())
(gdb) print f
$1 = (FRAME_PTR) 0xf43590
(gdb) n
1128          for (frames = Vframe_list;
(gdb) 
1134              this = XCAR (frames);
(gdb) 
1139              if (FRAME_WINDOW_P (XFRAME (this)))
(gdb) 
1141                  x_sync (XFRAME (this));
(gdb) 
1142                  FRAME_SAMPLE_VISIBILITY (XFRAME (this));
(gdb) 
1146              if (FRAME_VISIBLE_P (XFRAME (this))
(gdb) 
1151                count++;
(gdb) 
1130               frames = XCDR (frames))
(gdb) 
1128          for (frames = Vframe_list;
(gdb) 
1134              this = XCAR (frames);
(gdb) 
1139              if (FRAME_WINDOW_P (XFRAME (this)))
(gdb) 
1146              if (FRAME_VISIBLE_P (XFRAME (this))
(gdb) 
1151                count++;
(gdb) 
1130               frames = XCDR (frames))
(gdb) 
1128          for (frames = Vframe_list;

Continuing.


Evaluating (frame-list) gives

(#<frame emacs@qcore 0xf43590> #<frame F1 0xb6e7d0>)

I have no idea what frame F1 is. The only displayed frame is
`emacs@qcore', which is what `emacsclient -c -n' creates.

Just to reiterate, this is with `emacs -Q --daemon'.
