[Bug 1185330] Re: network manager error

[Mathieu Trudel-Lapierre]

** Description changed:

+ [Impact]
+ Users of broadband (ModemManager1, new version of ModemManager), Bluetooth PAN, CDMA devices, and other such connection methods.
+ 
+ [Test Case]
+ 1. Restart NetworkManager while an affected device is present and/or connected:
+ sudo restart network-manager
+ 
+ Alternate test case:
+ 1. Switch between devices: disconnect wifi and connect a CDMA dongle to the mobile network, or vice versa.
+ 
+ Without the fix, nm-applet should crash. With the fix, there should be
+ no crash.
+ 
+ [Regression Potential]
+ Since this changes the memory management of some pointers in nm-applet/network-manager code, there is a potential to introduce a memory leak if this code is left in place while other parts of the patch (such as how the connection ID string is built) is changed. Otherwise, since this was attempting an action which was obviously wrong, the potential for regressions is quite low.

  1. network manager crashes while switching between wifi to reliance dongle and vice a versa
  i also experienced the same in wifi to lan wired connection
  the network manager icon in top right corner vanishes and the network manager starts behaving weirdly
  
  2. i have configured reliance dongle and given it a name reliance connection 1
  when i first insert the dongle and it gets detected it shows proper name of the available connection in network manager drop down list
  then when i disconnect the network and join wifi and then again disconnect wifi and come back to reliance network it shows weird names or no title in the drop down list
