Aborted

this only happen when one installed wireshark(and wireshark-qt) without installing wireshark-gtk, but wireshark-gtk is an optional dependency

What's the status of this bug?

Can we get it fixed? Thanks!

Hi, can you still reproduce this issue? If so, what package and distro version? You can use this command to find out:

    apt-cache policy wireshark-qt

To obtain a trace, use:

    gdb -q -ex r wireshark

Once it crashes, use the "bt" command (without quotes) to obtain a backtrace.
