I am trying to hack a way to run two instances of Sylpheed simultaneously. Of course Sylpheed is designed to prevent this from happening.

Sylpheed is using some kind of dbus or proc check to identify a already running instance and switch to it. Does anyone know how to disable this, perhaps with a shell environment variable or some kind of redirection filter?

There is one big problem: If you are able to run them at the same time,
they will interfere each other regarding configuration files.

What is the reason you want to run 2 instances?

It doesn't matter why. It only matters how. The goal is to figure out exactly how Sylpheed is doing the instance lock so I can override it. I don't want to fiddle with workarounds that involve convolution. I just want to hack the instance lock.

I already know I can run it as another user and share the x-server. I have even done it this way in the past. I don't want to do it that way.

I have two instances in sandboxes, which could run at the same time without using the same configuration directory. But they can't run at the same time because of the single instance lock which currently evades my understanding. Even blocking DBUS and seccomp doesn't mitigate the instance lock. Strace is not helping me, either.
