Sentry Crash Report:

Description Robert LeBlanc 2017-03-07 18:48:56 UTC 
Application: kde5-nm-connection-editor (5.8.4)

Qt Version: 5.7.1
Frameworks Version: 5.28.0
Operating System: Linux 4.9.11-rleblanc201702041 x86_64
Distribution: Debian GNU/Linux 9.0 (stretch)

-- Information about the crash:
I opened the manage network connections from the network applet. I then selected "Add" and then "Import VPN". I selected my ovpn file and it asked if I wanted to copy the certs over. I said yes, and then got a message saying that the files already exists. The first time my certs were not there so the message didn't show up that time. I then get the crash before the wizard finishes. The first time, my config was there, the second time (I deleted the profile to recreate the bug) it did not show up.

The crash can be reproduced every time.

-- Backtrace:
Application: Connection editor (kde5-nm-connection-editor), signal: Segmentation fault

Sorry, drkoqi said that the bug didn't save.
Comment 4 Jan Grulich 2018-01-02 09:58:43 UTC 
Is this still reproducible with Plasma 5.11?
Comment 5 Christoph Feck 2018-01-18 00:32:16 UTC 
If you can provide the information requested in comment #4, please add it.
Comment 6 Robert LeBlanc 2018-04-12 19:26:48 UTC 
I just tested on Debian Buster and it seems it is no longer crashing the VPN wizard. Closing the setting window is causing a crash, but the VPN saves and works properly.

KDE Plasma version: 5.12.4
KDE Framework version: 5.44.0
Qt version: 5.9.2
Comment 7 Jan Grulich 2018-05-28 11:35:54 UTC 
I think this is or was a common bug on Wayland and I think it's already fixed.
