Actually this isn't quite right:

(gdb) 
-break-insert main
^done,bkpt={number="1",type="breakpoint",disp="keep",enabled="y",addr="0x080484d9",func="main",file="myprog.c",line="55",times="0"}
(gdb) 
-data-list-changed-registers
&"No registers.\n"
^error,msg="No registers."
(gdb) 
-exec-run
^running
(gdb) 
*stopped,changed-registers=[],reason="breakpoint-hit",bkptno="1",thread-id="0",frame={addr="0x080484d9",func="main",args=[{name="argc",value="1"},{name="argv",value="0xbffff794"}],file="myprog.c",fullname="/home/nick/myprog.c",line="55"}
(gdb) 
-data-list-changed-registers
^done,changed-registers=["1","3","4","5","6","7","8","9","10","11","12","13","24","26","40","41"]
(gdb) 


I think the changed-registers=[] after *stopped occurs because an exception is
raised in register_changed_p in the _first_ call to
mi_cmd_data_list_changed_registers and control doesn't return to to call
do_cleanups (cleanup).
