Tor Browser can't launch Tor or modify torrc when there's another Tor Browser instance running in another session on Linux

How to reproduce:

  1. Open user account 1
  2. Launch Tor Browser and let it bootstrap and stuff (used sandboxed-tor-browser but I guess same results will happen with the regular stuff)
  3. Switch to another user account 2
  4. Open Tor Browser there.

Can something be done in this case?
