geolocation demo getting javascript error on safari

[GoogleCodeExporter]

What steps will reproduce the problem?
1. using safari 5.1.7 on windows 7 or mac os/x 10 or safari on ios4 or ios5
2. go to http://www.brython.info/gallery/geoloc.html
3. click allow sharing of location

What is the expected output? What do you see instead?

Your position, along with latitude, longitude etc.
Instead, it only displays Your position and I get a javascript error:
undefined
TypeError: TypeError: TypeError: %f format : a number is required, not <class 
'NoneType'>
module '__main__'line 13...

Same error in Chrome. It seems to be happening when it can't detect one of the 
attributes, and so crashes when it calls %f on NoneType.

Little rewrite to make it look nicer, and it works in chrome and on android 
like this:

geo = win.navigator.geolocation

def navi(pos):

    xyz  = pos.coords

    data = {
            'lat':xyz.latitude,
            'lon':xyz.longitude,
            'acc':xyz.accuracy,
            'timestamp': pos.timestamp,
            'alt':xyz.altitude,
            'alt_acc':xyz.altitudeAccuracy,
            'heading':xyz.heading,
            'speed':xyz.speed
           }

    ul = UL()
    for key in data.keys():
        try:
            string = key + ': ' + str(float(data[key]))
        except ValueError:
            string = key + ': Could not detect'

        ul <= LI(string)

    doc <= H3("Your position")

    doc <= ul

def nonavi(error):
    log(error)

if geo:
    geo.getCurrentPosition(navi, nonavi)
else:
    alert('geolocation not supported')
