If you are running on a linux kernel this is a know bug, and fixed in the beta series. 
if you edit modules/FvwmCommand/FvwmCommandS.c replace
  SendText(Fd,"",0); /* tell fvwm that we are here */
with
  SendText(Fd," ",0); /* tell fvwm that we are here */
The problem is that linux pipes die on zero length packets.
