I created PPA for libappindicator trunk (on 2020-06-02) for 18.04 and 20.04, as in interim measure: https://launchpad.net/~timsc/+archive/ubuntu/libappindicator and this seems to work for me with discord (at least for a 2 hour call).
Strangely, my system didn't detect it as a update, so I manually did: sudo apt-get install libappindicator1=12.10.1+18.04.20200601.1-0ubuntu1 Probably something to do with package version numbers but I don't understand what. -- You received this bug notification because you are a member of DX Packages, which is subscribed to libappindicator in Ubuntu.

I ran into the issue yesterday when installing Discord for the first time. I have tracked the problem down to libappindicator passing in an extra vararg item to g_signal_emit that the signal's definition in libappindicator was not declaring, causing the crash you see above in gobject's g_signal dispatch machinery. Patch is attached. I am presuming this is 'upstream' for libappindicator, whatever that may mean for what appears to be an unmaintained project. If it is not, and since it is an Ubuntu/Canonical-sourced project originally, I respectfully request that you assist in upstreaming it since this bug is causing severe breakage for users across all distros.
