Trying to attach to non-existing primary application

[lennartack]

I sometimes get this error, even though no existing sioyek is running:

Creating shared memory block...

Secondary application attaching to shared memory block...

Secondary application successfully attached to shared memory block.
Secondary application cannot connect to IPC server.
Socker error:  QLocalSocket::ServerNotFoundError

I don't know how to debug this. I looked at shared memory blocks with ipcs but it doesn't contain anything from sioyek.

Perhaps it has something to do with a symlink of my .local directory to somewhere else?
