nm-plasma crashes plasmashell

[Silvio-frischi]

when trying to connect to a *new* network using plasma-nm, plasmashell crashes with the following message.

/usr/bin/plasmashell: symbol lookup error: /usr/lib/x86_64-linux-gnu/libplasmanm_editor.so: undefined symbol: _ZNK14NetworkManager18ConnectionSettings19autoconnectPriorityEv

You would need to ask your distro packagers to rebuild either networkmanager-qt or plasma-nm against current NetworkManager version.

Status changed to 'Confirmed' because the bug affects multiple users.

I think this is fixed now

I have the same problem in Kubuntu 15.10 upgraded from Kubuntu 15.04. I still use kernel 3.19 because the video card behavior with kernel 4.X is not good.

When I try to add a new connection:

> kde5-nm-connection-editor
Invalid service name "/org/kde/kde5-nm-connection-editor" using: "/org/kde/kde5nmconnectioneditor"
plasma-nm: Item "Nexxt_520B58" : active connection state changed to 2
networkmanager-qt: void NetworkManager::NetworkManagerPrivate::propertiesChanged(const QVariantMap&) Unhandled property "Devices"
networkmanager-qt: void NetworkManager::NetworkManagerPrivate::propertiesChanged(const QVariantMap&) Unhandled property "PrimaryConnectionType"
plasma-nm: NetworkManager state changed to 7
kde5-nm-connection-editor: symbol lookup error: /usr/lib/x86_64-linux-gnu/libplasmanm_editor.so: undefined symbol: _ZNK14NetworkManager18ConnectionSettings19autoconnectPriorityEv

I have to reinstall the OS?

I have reported the bug to kde bugs. https://bugs.kde.org/show_bug.cgi?id=355501

The upstream Bug was already in the original post. And it was fixed for me a long time ago.
