This usually indicates that a BLOCK_INPUT is missing somewhere in  
Emacs.  What you need to do is start emacs under gdb in the Emacs  
source directory.  Then in Emacs you call the function x-synchronize  
with a t argument, for example evaluate in the *scratch* buffer:
(x-synchronize t)

When gdb hits the breakpoint in the x_error_quitter function (that  
breakpoint is inserted by .gdbinit in the emacs source directory),  
print a stack trace from within gdb and mail it here.
