>Description:
	I upgraded my laptop and a desktop to yesterday's -current.  I'm
	now having trouble running certain X applications over ssh.

	The laptop uses XFree86 4.4.0; the desktop uses xorg.
	I did not upgrade X on either machine.  If I log in from my desktop
	to my laptop via ssh (with X forwarding -- it's all done by scripts
	that haven't changed), I can't fire up (for example) exmh, acroread5,
	or psi.  With the first two, the startup fails completely.  I get

	X Error of failed request:  BadAtom (invalid Atom parameter)
	  Major opcode of failed request:  18 (X_ChangeProperty)
	  Atom id in failed request:  0x182
	  Serial number of failed request:  137
	  Current serial number in output stream:  138

	with acroread5 (via Linux emulation, of course) and

	X Error of failed request:  BadAtom (invalid Atom parameter)
	  Major opcode of failed request:  18 (X_ChangeProperty)
	  Atom id in failed request:  0x184
	  Serial number of failed request:  12
	  Current serial number in output stream:  15

	for exmh (native).  

	psi is rather weirder -- I get lots of mesages like this, every few
	seconds:

	X Error: BadWindow (invalid Window parameter) 3
	  Major opcode:  2
	  Minor opcode:  0
	  Resource id:  0x40

	but it fires up.  (The messages continue while psi is running.)  When
	I exit, I get 

	X Error of failed request:  BadWindow (invalid Window parameter)
	  Major opcode of failed request:  2 (X_ChangeWindowAttributes)
	  Resource id in failed request:  0x40
	  Serial number of failed request:  20747
	  Current serial number in output stream:  20767

	On the other hand, I can fire up some X applications, such as xterm
	and xwininfo.  I can run xmms successfully, but when it exits it says

	Gdk-ERROR **: BadAccess (attempt to access private resource denied)
	  serial 2977 error_code 10 request_code 102 minor_code 0

	Switching to an older version of ssh solves the problem, which
	strongly points to the trouble area.
