Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a valgrind log following the instructions at https://wiki.ubuntu.com/Valgrind and attach the file to the bug report. This will greatly help us in tracking down your problem.

$ G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind -v --tool=memcheck --leak-check=full --num-callers=40 --log-file=valgrind.log nm-connection-editor

After few minutes the program memcheck crashed. I attach the log results (may incomplete due the crash).
I guess nm-connection-editor crashes when trying to save something to the keyring, so the problem may be in NM <-> gnome-keyring interaction.

Changing to confirmed since I have been able to reproduce the error.
