New issue 246 by j... at kitenet.net: ewmhDesktopsLogHookCustom throws(?)  
Maybe.fromJust: Nothing

What steps will reproduce the problem?
1. use ewmhDesktopsLogHookCustom to filter out a WS
2. change focus
3. see xmonad output "Maybe.fromJust: Nothing" to stderr (.xsession-errors)

What is the expected output? What do you see instead?

no obscure stderr output expected :-)

What version of the product are you using? On what operating system?

0.8 on Debian unstable

Please provide any additional information below.

If this error is due to a module from XMonadContrib, please tag this issue
with 'Component-Contrib' below.


My relevant config is this, to filter out the scratchpad workspace in gnome:

logHook = ewmhDesktopsLogHookCustom $ filter $ \w -> W.tag w /= "SP"

I see two uses of fromJust in ewmhDesktopsLogHookCustom, not sure which is
getting an unexpected Nothing.
