Thanks for the pointer, I've now got this giving me the right line number when an exception occurs, although I still get an empty stack trace from

print "Stack Trace:\n%s\n" % str(traceback.print_exc(2))

inside the excepthook.

Any ideas why this is?

Is there no traceback since the traceback was fed to the excepthook? Is there another way of getting the traceback like you see when the exception isn't caught?

Thanks for the help.

The problem is that the excepthook gives the line of the topmost called
function rather that the actual line that generated the error the way
you get it with a normal traceback.
    

A look into the traceback module shows that tracebacks are stored as a
linked list. Here's a way to get hold of its tail:

def tbiter(tb):
    while tb is not None:
        yield tb
        tb = tb.tb_next

def last(items):
    for  item in items:
        pass
    return item

# example usage
def myexcepthook(type, value, tb):
    tb_tail = last(tbiter(tb))
    print tb_tail.tb_lineno
