More information.  The gnome-terminal does NOT exbhibit this bug.  But
uxterm, based on XTerm(268) does show the bug.  Hmm... I just
installed a whole bunch and did some simple tests.

	  Terminal Emulator 	Status
	  -----------------	--------
	  eterm			ok
	  evilvte		bad, can't size down, only up.
	  gnome-terminal	ok
	  guake			ok
	  konsole		ok
	  kterm			bad
	  kxterm		ok, wierd
	  lxterminal		ok
	  mlterm		ok
	  mrxvt			ok
	  mrxvt-full		ok
	  rxvt			bad
	  tilda			non-resizeable 
	  uxterm		bad
	  wterm			bad
	  xiterm		bad

So I'd almost say it's something with the xterm family, maybe Xlib
based?

Let me know if there's more info you need and I'll do my best to get
it to you.  I'm happy to apply patches or updates to the system too.
I'll be pulling daily updates and doing full reboots.

THanks,
John
