The exception is a canary that's meant to warn us about singletons being reused in violation of their expected lifecycle.

The log shows that TorPlugin and PollerImpl were already running before BriarService was created. The database must have been open too, as the poller was able to load a contact's transport properties.

It looks like a new BriarService instance was created when one already existed, or used to exist. The BriarService instance also has a canary to check for reuse, so this must be a new instance.
