Comment 3 for bug 587795

This looks very much like the bug I see on a regular basis. I'm using Windows XP, bzr 2.2.1, and a pack-0.92 repository. On occasion when I "bzr pull" to bring in changes from other developers, I get this:

-----
Using saved parent location: N:/bzr/main/code/
bzr: ERROR (ignored): 'file:///C:/Tableau/.bzr/repository/upload/aphtssjcbh20hqj6xeuv.pack'
bzr: ERROR: File exists: u'C:/Tableau/.bzr/repository/upload/aphtssjcbh20hqj6xeuv.pack': [Error 183]
 Cannot create a file when that file already exists

The log shows the following:

The offending pack file is indeed present in the upload directory. If I simply retry the "bzr pull", it always completes successfully.

The pull is moving data from an SMB share to a local repository on an NTFS partition.
