Hello.

The release of Ubuntu I am using: Ubuntu 13.04
The version of the package I am using: 0.9.8.0-0ubuntu6

I am using a Dell Inspiron 5520 laptop. And in order to connect to the
Internet, I use my Samsung SGH-L700 phone as a Bluetooth modem. When I
try to connect to the Internet via Bluetooth DUN connection using
Network Manager applet, there is usually no problem. But when I try to
disconnect,

What I expect to happen: The connection should be terminated and the
system should go on working normally.

What happens instead: Suddenly, a black screen with full of text comes
up. Sometimes (not always) a "panic occurred" message with a blinking
Caps Lock light can be seen.

Additionally, after establishing the connection, the name of the
connection isn't viewed on the applet's drop-down menu as it should be.
Sometimes there is a strange character, sometimes the text "Empty tag",
sometimes a text that is not about the connection's name such as
"org.freedesktop. ..." or "Connect to a Wi-Fi _network" is seen instead
of the name.

Before reporting this bug, I opened a topic on Ubuntu Turkey Forum. A
forum moderator recommended me to file a bug report about network-
manager package on Launchpad. So I filed a report here. This is my first
bug report.

Thanks for possible solutions in advance.
