I'm getting the same error and was unable to access any websites, I had to downgrade networkmanager and libnm-glib to version 1.0.2-4 in order to get the connection and web access back to normal.

After every reboot I have to restart NetworkManager to get it working.

same problem, attached log extract
networkmanager keeps crashing and restarting, not possible to establish network connection.

For segfaults, please get traces from `gdb --args NetworkManager --no-daemon` and rebuild packages with debug symbols until the traces are useful.

I'm experiencing a weird variant of this -- when activating openconnect after connecting to my WPA2 Enterprise (at work) on a Dell E7440, my SSL access over the VPN link just stalls 100%. I tested with everything from cURL to Thunderbird to simply Firefox+Lastpass (trying to log in). The non-SSL access seems to work, but as soon as the SSL kicks in (think STARTTLS) it all dies. Downgrading from 1.0.4 to the latest 1.0.2 packages of networkmanager and the applet (just those 2) and everything is back to working normally.

Sadly, no logs that point a finger (crashes, ugly errors, etc.) that I see -- the best I was able to get was cURL initiating the TLS 1.2 handshake, get an initial reply then... hang until the timeout happens and a Protocol error is emitted.

Since the upgrade, I experience the same issue of being unable to visite SSL sites. After manually dropping the MTU (1406 for my connection) everything returns to working normally. Did mtu auto discovery stop working?

I found these 2 links as reference:

From those bug reports I see the bug seemed to be fixed in more recent versions of NetworkManager. I believe this bug was fixed in this commit:
https://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?h=nm-1-0&id=105e30efbaf422401902575749efdcd18706ace1
Can somebody report back just to confirm this is fixed. Thanks.

Completely unscientific ad-hoc feedback, the same network at work (from the above comment) that I had problems with has been stable for awhile. Unfortunately it's a large meshed proprietary vendor and the IT staff may have upgraded all the firmwares as well which could skew results. But generally speaking, I've not had problems lately with the latest NM releases. $0.02.
