AIUI the versioning will solve it. This looks awfully like the usual  
slow-server situation to me:

1. Potlatch sends way to server
2. Server does it, but freaks out halfway through operation and  
doesn't return success code to Potlatch
3. Potlatch eventually puts up "/!\" to say "The connection is  
broken" and offers a retry button
4. User clicks retry
5. Repeat from step 1 ad infinitum

With 0.6, the version number should be incremented at step 2, so  
there'll be a conflict if the user retries.
