Yet another BizTalk error

Your BizTalk installation worked like a charm, but suddenly you receive errors like this?

There was a failure executing the receive pipeline: "PipelineName, PipelineAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=..." Source: "Init Message Processing Properties" Receive Port: "..." URI: "..." Reason: Loading property information list by namespace failed or property not found in the list. Verify that the schema is deployed properly.

In my case, and, as it seems, some others, this was caused by corrupted installation of third party adapters for BizTalk. Reinstallation of adapters solved the problem.
