You are calling spawnPipe in you startup hook

    > myStartupHook :: X ()
    > myStartupHook = do
    >   xproc <- spawnPipe ("xmobar -x 0")
    >   […]

but you never do anything with that pipe; e.g., normally you would feed
information about the workspaces to xmobar.  Note that, in particular,
this

> in my xmobar.hs it is called via xproc inside my main do block.

is not quite right.  xproc is simply a name you give to the handle
returned by spawnPipe.

Whether you want to use pipes or not, I would suggest going through the
tutorial[1] to learn how to correctly set up xmobar.  It also tells you
a little bit about Haskell, which may be useful when you have to debug
something again in the future.
