Description Christopher Griffiths 2015-04-13 17:32:27 UTC

Application: kde-nm-connection-editor (0.9.3.4)
KDE Platform Version: 4.14.3 (Compiled from sources)
Qt Version: 4.8.5
Operating System: Linux 3.18.11-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
I opened the Connection editor to configure additional settings as required by my configuration. I clicked on the network's name and then on to "Edit...", this crashes Connection editor. I have repeated it four times and every time it has crashed including when I have disconnected from the WiFi network in question.

- Unusual behavior I noticed:
My system's hostname is set by hostnamectl [part of systemd] to "taliesin" however after connnecting to the wireless network in question it changes my hostname to what the local network assigns my machine. I have changed this information back to taliesin after connecting to the network otherwise I cannot launch KDE applications due to dbus getting confused with the new hostname.

The crash can be reproduced every time.

-- Backtrace:
Application: Connection editor (kde-nm-connection-editor), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

New crash information added by DrKonqi

kde-nm-connection-editor (0.9.3.4) on KDE Platform 4.14.3 using Qt 4.8.6

- What I was doing when the application crashed:

Trying to open the configuration window of a connection; any connection crashed.

- Custom settings of the application:

I installed a second Wifi adapter and used it instead of my other adapter to connect to the same network; this created an entry with the same name as the one used with the other adapter. I was planning on modifying the names to disambiguate them and then encountered this crash.
