Do you happen to know how to trigger the crash?
I hit this crash as well. I will try to run nm-applet with valgrind.
Created attachment 1068118 [details] Output from valgrind It looks like use after free error. I'm not sure about security impact therefore I marked this attachment as private. You can change it to public after analysis.
I could not reproduce. But I found the problem thanks to the valgrind log. Thanks, Lukas :) The issue has been fixed upstream: master: 0d0e843 libnma/libnm-gtk: fix a possible crash on widgets destroy (rh #1254043) nma-1-0: 6ee38dd libnm-gtk: fix a possible crash on widgets destroy (rh #1254043)
