Bug comments restored from Gmane.org:

using Kazaalite with builtin comctl32, if i try to sort a treeview by clicking 
on a column title, wine wont sort it and prints this message

err:treeview:TREEVIEW_Sort invalid item hParent=0

as a temporary workaround, i changed the following in TREEVIEW_Sort() from 
treeview.c

/* Check for a valid handle to the parent item */ 
   if (!TREEVIEW_ValidItem(infoPtr, parent)) 
   { 
        ERR("invalid item hParent=%x\n", (INT)parent); 
        return FALSE; 
   }

to  
    /* Check for a valid handle to the parent item */ 
   if (!TREEVIEW_ValidItem(infoPtr, parent)) 
   { 
        ERR("invalid item hParent=%x\n", (INT)parent); 
        /* return FALSE; */ /* i still requested a sort.... */ 
        parent=infoPtr->root; 
   }

which does the trick for now, and all columns sort as you would expect.
