[web2py] compileapp error

[topher.baron]

An ajax request I'm making is erroring on the server with in a place
that it shouldn't.

Here is the ticket :

Traceback (most recent call last):
  File "gluon/main.py", line 508, in wsgibase
  File "gluon/main.py", line 206, in serve_controller
  File "gluon/compileapp.py", line 435, in run_controller_in
TypeError: 'NoneType' object is not callable


Here is the controller method that is called :

def addNewick():

    tree = None

    try:
        import applications.tred.modules.newick as newick
        reload(newick)
        tree = newick.parse( request.vars.newickString )
    except:
        return 'parseError'

    import datetime

    treeId = db.tree.insert( name = request.vars.newickName,
                             comments = request.vars.newickComment,
                             creationDate = datetime.datetime.now() )

    db.sourceTreeMapping.insert( user_id = auth.user.user_id,
sourceTree = treeId )

    insertTreeNodes( { 'tree': tree, 'treeId': treeId } )

    return treeId



I've placed debugging lines throughout the function - all are printed,
so I'm guessing the error occurs after the return statement and
somewhere in the web2py framework

Any suggestions ?
