Hi People,
I am experiencing a bug in NetworkManager using rhel6:
As I saw a message asking me to report bugs in the mailing list I came here.
=)
uname -a
Linux localhost.localdomain 2.6.32-44.1.el6.x86_64 #1 SMP Wed Jul 14
18:51:29 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
h...@redhat ~$:rpm -q NetworkManager dbus
NetworkManager-0.8.1-2.el6.x86_64
dbus-1.2.24-1.el6.x86_64
Here is the backtrace. Unfortunately I don't have the debuginfo packages..
After the bt I describe how to reproduce.
Jul 22 17:07:12 localhost NetworkManager[4632]: <warn> caught signal 11.

**********************************
The code I used for getting access point information using python was:
import dbus
sys_bus = dbus.SystemBus()
nm = sys_bus.get_object('org.freedesktop.NetworkManager',
'/org/freedesktop/NetworkManager')
devices = nm.GetDevices(dbus_interface='org.freedesktop.NetworkManager')
device = sys_bus.get_object('org.freedesktop.NetworkManager', devices[1])
access =
device.GetAccessPoints(dbus_interface='org.freedesktop.NetworkManager.Device.Wireless')
ap = sys_bus.get_object('org.freedesktop.NetworkManager', access[0])
ap_props = dbus.Interface(ap, 'org.freedesktop.DBus.Properties')
props = ap_props.GetAll('org.freedesktop.NetworkManager.AccessPoint',
byte_arrays=True)
The error message it receives is:
DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name :1.88 was
not provided by any .service files
If I print ap_props I get:
>>> str(ap_props)
"<Interface <ProxyObject wrapping <dbus._dbus.SystemBus (system) at
0x1865cb0> :1.88 /org/freedesktop/NetworkManager/AccessPoint/1 at 0x199a190>
implementing 'org.freedesktop.DBus.Properties' at 0x199a1d0>"
Is there any other information I can give you?
Thanks!
