Bug 512543

Thanks for the crash report. If something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the coredumpctl command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl ?

Thanks.

Unfortunately, coredumpctl is not generating actual core files for nm-fortisslvpn-service (Storage: none), even though other programs on my system generate coredumps correctly.

I did a live capture with gdb, I'm hope it is useful, here is the output:

Thanks in advance

Thanks for the backtrace. Those more familiar with this will have to look further into it.

This paints a picture of the software failing to handle an unexpected disconnection from the plugin.
