Running wireshark-gtk with lots of virtual devices and it crashed with SIGSEGV

[Thomas A. F. Thorne]

I tried to start up Wireshark on my Ubuntu 18.04.1 LTS system. I have a set of docker containers runnign with virtual networks setup. I think some of the containers are restarting frequently at presnet, causing churn in my device list. When try to start a capture, or even select a port to capture on Wireshark seemed very slow to respond and crashed before I could successfully start a capture.

bug450195 was suggested as a possible match for this but it is quite old with a fix supposedly released so I am opening a new ticket.

Having reviewed the contents of the attachments, I do not consider anything there sensitive so I am changing this bug from private to public.

If there is anything I could do to try and recreate the issue or debug the problem please let me know.

[Balint Reczey (rbalint)]

Wireshark upstream dropped support for the GTK UI. Could you you please check if you see the crash with the Qt UI, too? It is in the wireshark-qt package.
