nm-connection-editor crashed with SIGSEGV in g_closure_invoke()

[Robert Bruce Park]

I exported my VPN config from my other computer, and then attempted to import that config on this system. It crashed both times I tried.

Thank you for your report!

However, processing it in order to get sufficient information for the
developers failed (it does not generate a useful symbolic stack trace). This
might be caused by some outdated packages which were installed on your system
at the time of the report:

outdated debug symbol package for libnm-gtk0: package version 0.9.8.8-0ubuntu3 dbgsym version 0.9.8.0-1ubuntu5.1
outdated debug symbol package for network-manager-gnome: package version 0.9.8.8-0ubuntu3 dbgsym version 0.9.8.0-1ubuntu5.1

Please upgrade your system to the latest package versions. If you still
encounter the crash, please file a new report.

Thank you for your understanding, and sorry for the inconvenience!

Same error on import of .ovpn file. I have updated to current releases tonight and error persists.

[Felipe van Schaik Willig (felipevsw)]

Same error when importing my company's .ovpn saved config file. Before the import I dist-upgraded.
Why is this marked as invalid?

[Felipe van Schaik Willig (felipevsw)]

I changed the status from Invalid to New because this issue is not invalid. Forgive me if I overstepped boundaries, but less than a month away from the release, this issue will make the new version unusable for me (and I bet for a lot of people as well).

[Launchpad Janitor (janitor)]

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

[Faris Chebib (octaflop)]

Can confirm that importing an .ovpn which works on 13.10 just crashed my window.

[Hereinoz (davrosjos)]

The VPN can be set up using the manual process, entering the locations of the certificate files, etc. It is just the import process which is not working.

[Felipe van Schaik Willig (felipevsw)]

Even using the manual process instead of the import one, it's still a little messy for me. I can't select more than one certificate file. After I select the first one, the next one I select make the previous selection "disappear", so I have to select it again, but then the other one disappear, and so on... I still can't configure it.

[Francesco Astegiano (francesco-astegiano-7)]

Also affecting 14.04 gnome beta 2 both using nm-connection-editor and network-manager-applet, it just crashes as soon as the ovpn file is imported.

Manual configuration also doesn't work, it goes into loop when importing p12 file with error
(nm-connection-editor:8645): Gtk-CRITICAL **: gtk_file_chooser_select_filename: assertion 'filename != NULL' failed

[Alberto Salvia Novella (es20490446e)]

It renders essential functionality of the package (or a dependent one) broken.

[Leon (leonbo)]

I'm having the same issue. Importing a previously export .ovpn file crashes the applet. Manually recreating the configuration is impossible because when you selectie a .p12 file the gui becomes unresponsive.

[neilpryde (neilpryde)]

Exactly the same behaviour. After selecting the first p12 file, the cpu load goes up to 100% for the nm process.

[Jonathan MIlls (jonmills-b)]

This bug affects me also. I have a clean 14.04 install. Five different OpenVPN profiles, all that worked in 13.10. The window crashes during import. We also run an OpenVPN Access Server -- like the commercial variety SSL VPN. This exports ovpn profiles with inline base64-encoded certs. nm-connection-editor chokes on this also.

[Kamal Lakis (kamlakis)]

same problem here on importing both openvpn configuration (.ovpn) and vpnc configuration (.pcf)

please note that both packages network-manager-openvpn and network-manager-vpnc was installed and those configurations was working fine with previous versions of ubutnu

[Traxpoint (traxpoint)]

After reading in a config.ovpn it crashes.
dmesg out:
nm-connection-e[9712]: segfault at a8fc50 ip 0000000000a8fc50 sp 00007fffd02726c8 error 15

[Mathew Yanovsky (mathew-yanovsky)]

Similar problem after trying to set up OpenVPN connection manually: after selecting .p12 key file as a 'User certificate:'. CPU load goes to 100% and NetworkManager responds poorly until the configuration window is closed. There is no way to save such a configuration.
Ubuntu 13.10:
network-manager 0.9.8.0-0ubuntu22
network-manager-gnome 0.9.8.0-1ubuntu5.1
network-manager-openvpn 0.9.8.2-1ubuntu2
network-manager-openvpn-gnome 0.9.8.2-1ubuntu2

[Niclas Lockner (niclasl)]

Output from Valgrind before the crash

[Felix Bouleau (felixfelox)]

I'm also having this problem - anything I can do to help? Running Xubuntu 14.04.

[Carlos Tavares Jr (carlosmtavaresjr)]

Same issue here. I already reverted back to ubuntu 12.04 lts as I need openvpn for my work. Any fix available?

[Ole Jon Bjørkum (olejonbj)]

Having the same problem on Ubuntu 14.04. Creating the connection manually through nm-connection-editor works fine, but importing makes it crash.

[gumaflux (l-infs-g)]

Same problem on Ubuntu 14.04, importing configuration causes Network Manager Applet to crash.

[Leon (leonbo)]

When selecting my .p12 file from nm-connection-editor I get a lot of these errors:

** (nm-connection-editor:10357): WARNING **: Invalid setting VPN: remote
** (nm-connection-editor:10357): WARNING **: Invalid setting VPN: remote

Causing the 100% cpu usage.

[pheidrias (5-launchpad-net-pheidrias-info)]

Cannot add profile, too. Interestingly, I was able to add a profile on my other PC some time before, when using Ubuntu GNOME 14.04 beta version!
So the bug may have come into game between beta and todays Ubuntu GNOME !

I do get
kernel: [33342.541455] nm-connection-e[17696]: segfault at 125a700 ip 000000000125a700 sp 00007fffacbee168 error 15
and the corresponding crash after some second after having selected a .pcf file (cisco).

When I try to connect to a manually setup VPN, it gives it a try, but fails after some seconds:

Another "Fun Fact": The "working" version on my other PC cannot cope with saved passwords (would not connect - only when entering the password each time) - but I suppose that's another (Gnome Keyring feat. Heartbleed?) problem...
