Local fetch hangs in Eclipse

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a local clone, i.e. a file system URL
2. Perform an incremental fetch later on, when there are changed

What is the expected output? What do you see instead?
- I'd expect the clone to finish. Instead it hangs. Not always, but often.
