Symptoms

The K2 service is starting normally (almost), but the workflow manager isn't available.
The workflow server node in Workspace-console Management is not working.
Also PandampD is not working properly. Deploy filas with the same error.

Resolution

Extra DLLs (from a community project, a service broker) have been added to GAC by error. In fact, every DLLs from the project have been GACed.
Once the extra assemblies removed from the GAC, the server is completly functionnal again.
