[Xmonad] [BUG] tabbed layout and state dumps

[Robert Manea]

Hello,

there seems to be some bug in Tabbed.hs that makes it print error
messages. While this is no big thing it makes using the state dump as
workspace indicator pretty useless.

Errors occur on every state change:

	BadDrawable (invalid pixmap or window)
	BadGC (ivalidGC parameter)
	...
	and some more

See here for a shot of it: http://omploader.org/file/tabbed-errors.png
Note the upper left corner.

Bye, Rob.
