Extract from /var/log/messages showing the crash, with backtraces

Description of problem:

Running on Fedora 15 with NetworkManager-0.8.999-3.git20110526.fc15.i686.

After adding a configuration for a Cisco VPN, Network Manager crashes and fails
to start at reboot.  /var/log/messages (relevant part attached, with debuginfo backtraces) shows that Network Manager is getting an exception while
parsing the VPN connection keyfile:

May 28 11:38:55 localhost NetworkManager[766]:    keyfile: parsing VPN connection 1 ... 
May 28 11:38:55 localhost NetworkManager[766]: <warn> caught signal 11. Generating backtrace...
May 28 11:38:55 localhost NetworkManager: ******************* START **********************************

It is necessary to remove the connection file from /etc/NetworkManager/system-connections/ before NetworkManager will successfully start.

Version-Release number of selected component (if applicable):

Running on Fedora 15 with NetworkManager-0.8.999-3.git20110526.fc15.i686.
[dlkrejsa@localhost ~]$ rpm -qa | grep NetworkManager

How reproducible:


Steps to Reproduce:
1. In Network System Settings, add a VPN connection (by clicking on the
   plus sign under the existing Wired / Wireless / Network proxy / etc.
   listings -- pet peeve: this is much harder to find than in the older gui),
   selecting 'VPN' from the interface list (it's the only option) and clicing
2. Choose 'Cisco Compatible VPN (vpnc)' connection type. Click Create..
3. Enter Cancel VPN settings (where's the option to import from a .pcf file?)
   I entered the Gateway, Group name, and used a 'Saved' Group password,
    no User password, and unchecked 'Available to all users'.  Click Save.

Actual results:

Network Manager crashes and won't restart after reboot or logout.

Expected results:

New VPN configuration should be available for use and Network Manager should
not crash.

It also happens with OpenVPN connections.
Comment 3 Dan Krejsa 2011-05-28 15:48:38 EDT
In step 3, 'Enter Cancel VPN settings' should just be 'Enter VPN settings'.
Comment 4 Danila Migalin 2011-05-29 01:24:30 EDT
Have a same problem with OpenVPN connection

After removing the connection file from /etc/NetworkManager/system-connections, NetworkManager can be restarted and works normal.
Comment 5 Lukas Zapletal 2011-05-30 03:34:57 EDT
I confirm this. I am also unable to recreate the setting again. Getting the same signal again.

Comment 6 Michael Ekstrand 2011-05-30 12:15:21 EDT
Looks to me like this is the same problem as https://bugzilla.redhat.com/show_bug.cgi?id=625047.

This introduces a major regression into Fedora 15 - I had about a half-dozen network configs that had to be moved out of the way before NetworkManager would start after updating.  It doesn't just apply to VPN configs - I am seeing the same with wireless network configurations as well.
Comment 7 Toby Haynes 2011-05-30 13:36:05 EDT
Creating a VPN session with a name _without_ any spaces appears to work - I can't do a full test until I get home. Given that the DEFAULT name is "VPN Connection 1", you must alter this before saving.
