The machine where the error showed up can't get two different strings in a row. It's a backup server, so I'm the only one using it for test purposes, which is why I did not notice the error before; it may have been present for a long time. Below is what is installed on each machine, the first one (arsene) being the faulty one; it is a rather old Dell desktop, the others are dedicated servers in datacenters, such as kimsufi.com, online.net.
