Cant connect to an Access point (Unicode traceback)

[garycmartin]

In 13.1.0 build 6, trying to connect to an Access Point via the Neighbourhood view fails, generating the below Traceback

Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/jarabe/desktop/meshbox.py", line 496, in _ap_props_changed_cb

As a temporary quick & dirty hack, I added this one line to get connected for now, likely only works as the ssid's I connect to are plain ascii, no unusual unicode characters:

ssid = str(ssid)
display_name = unicode(ssid, encoding)

Retesting in 13.1.0 build 7, no problem now in connecting to access points. Looks like this can be closed if someone else can confirm.

I agree, this was fixed in [PATCH] Request AP properties with dbus ByteArrays (#4031)

Test case: connect to any type of wireless network, check that the tray icon shows that the connection has completed, check that the shell logs don't include this error:

TypeError: coercing to Unicode: need string or buffer, dbus.Array found

We can connect to 802.11 APs in OLPC 13.1.0 os7 and the TypeError message mentioned was not found in any logfiles.
