Problem with wxGridCellAttr. Important!!!

I have got a problem whith wxGridCellAttr object.

I'm trying to make loop over columns of a wxGrid object, where in each
loop I build a wxGridCellAttr with differents fonts and colours and I
call SetCollAttr method. I don't know why this fail in an iteration (not
always the same). It's not an controled exception but windows throws a
memory error.

What I try to do is something like this (well a bit more
complicated...):
grid = wxGrid(self)
grid.CreateGrid(5,5)
colors = [wxWHITE,wxBLACK,wxLIGHT_GREY,wxRED,wxBLUE]
for col in xrange(5):
      attr = wxGridCellAttr()
      attr.SetTextColour(colors[col])
      attr.SetBackgroundColour(colors[col])
      grid.SetColAttr(col,attr)

If somebody knows what's happening with this piece of code please reply
me. Thanks

I thought it should be doing it interally, but try calling attr.IncRef()
