[Haskell-cafe] gtk2hs treeview problem (Windows)

I installed ghc 6.6.1 and I'm trying to use the tree view widget.
To enable search in treeview, I added following 2 lines:

  New.treeViewAppendColumn view col3

  -- my addition
  New.treeViewSetEnableSearch view True
  New.treeViewSetSearchColumn view 0

in demo/treeList/TreeDemo.hs

The program crashes if I press any key. The console shows:


(TreeDemo.exe:3064): GLib-GObject-WARNING **: gtype.c:3339: type id `0' is inval

(TreeDemo.exe:3064): GLib-GObject-WARNING **: can't peek value table for type `<
invalid>' which is not currently referenced

I also tried ghc 6.8.1 with the same result. Any hints? Thanks.
