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.
