[Comment from a bug triager]
From bug 257706:
Plasma crashed after trying to use Network Manager
- What I was doing when the application crashed:
Trying to activate network.
Network manager service reported as Dead. Manually using dhclient, I can use
the network, but trough the plasma network manager, I can not.

Comment 8 Edward Nygma 2011-04-01 14:43:01 UTC 
This does not look resolved to me. As you can see, I reproduced the bug in the comment above.

Additionally, bug #267294 (duplicate) was reported in February 2011, so I don`t know how effective the November 2010 patch was.

I am still getting such crashes occasionally and will report as much as possible.

Thanks.
Comment 9 Lindsay Smart 2011-04-01 20:48:14 UTC 
It's still present for me, but it might be possible that the fix is not in the updates that automatically come from the Ubuntu repositories.

Is there a command I can run to see if the version I have is the one that contains the fix in comment #4 or not?

Comment 11 Lamarque V. Souza 2011-06-02 20:12:05 UTC 
I am not able to reproduce this bug in a recent Plasma NM snapshot. If nobody also can I will close this bug as fixed. Please keep in mind that some distributions is shipping very outdated Plasma NM snapshot from last year. When testing make sure it is recent Plasma NM snapshot. If you cannot assure that then it is better clone networkmanagement repository and compile Plasma NM yourself:

git clone git://anongit.kde.org/netwokmanagement
mkdir networkmanagement/build
cd networkmanagement/build
cmake -DCMAKE_INSTALL_PREFIX=/usr ..
make
make install
