Got the same problem. The following is printed in the terminal:

When I first tried it did not segfaulted until I tried opening the dashboard.

I've got the same config as @xiraix, except for the OS (I got Manjaro 20.1), and maybe for the pip installed packages (pip freeze at https://pastebin.com/QzkWEZmC).

Nonetheless, I was able to run gdbgui and open the dashboard without errors after downloading the binary in the repository's releases page.

Got the same problem. It may be that something is incompatible with greenlet v. 0.4.17. Greenlet 0.4.16 works fine.

A temp fix is to uninstall greenlet 0.4.17 after installing gdbgui and then install greenlet 0.4.16.

I did:

pip3 install gdbgui
pip3 uninstall greenlet
pip3 install greenlet==0.4.16

I was then able to run gdbgui and open the dashboard.
