Hi, I have this same problem on Ubuntu 18.04 i386, using an up-to-date bionic environment (main/universe/multiverse of bionic, bionic-updates and bionic-backports repos) .
I am attaching an apport service /var/crash log file. I couldn't find any network-manager-gnome dbg packages, so I'm not sure the backtrace will have symbols. If you need more information I am happy to help. Reproduction: Launch nm-connection-editor, then double-click a connection to modify it. Workaround: Install gnome-keyring (which recommended package, not a dependency) [1] Given 18.04 is the last Ubuntu release with i386 support, I am unable to move to a more recent Ubuntu release such as cosmic (or beyond) at this stage. I am developing a live CD used by many users who aren’t Linux experts, may have poor internet connection and may be using very old computers. Given it's a non-persistent environment, saving passwords with gnome-keyring is not useful, and the password prompt will likely cause much confusion. My intention is to provide an i386 version based on Ubuntu 18.04 until the maintenance support window ends in 2023 [2] [1] https://packages.ubuntu.com/disco/network-manager-gnome [2] https://ubuntu.com/about/release-cycle ** Attachment added: "_usr_bin_nm-connection-editor.999.crash" https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/1806269/+attachment/5296863/+files/_usr_bin_nm-connection-editor.999.crash -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-applet in Ubuntu. https://bugs.launchpad.net/bugs/1806269 Title: nm-connection-editor crashes when trying to modify connection Status in network-manager-applet package in Ubuntu: Incomplete Bug description: Thread 1 "nm-connection-e" received signal SIGSEGV, Segmentation fault. 0x00007ffff7ba6b53 in modules_initialized (object=<optimised out>, res=0x555556048a40, user_data=<optimised out>) at src/libnma/nma-cert-chooser-button.c:98 98 src/libnma/nma-cert-chooser-button.c: No such file or directory.
