This morning one of my customers ran into this error while merging two Accounts:
Not very descriptive and since the normal Download Log File button was disabled, also not a lot of help.
I turned on platform tracing and repeated the merge process so that I could hopefully capture the real error. Here is what showed up (in order of appearance):
Web Service Plug-in failed in SdkMessageProcessingStepId: {27CBBB1B-EA3E-DB11-86A7-000A3A5473E8}; EntityName: none; Stage: 30; MessageName: InitializeFrom; AssemblyName: Microsoft.Crm.Extensibility.InternalOperationPlugin, Microsoft.Crm.ObjectModel, Version=7.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35; ClassName: Microsoft.Crm.Extensibility.InternalOperationPlugin;

It was, of course, the final exception that was the key.
It turns out that both Account had Relationship Roles associated with them and I am assuming that the two sets of roles were incompatible with each other.
I removed the roles from the second Account and the merge was correctly performed.
