version 1.11 truncates filenames on win32

[Sven]

I downloaded the no-admin version (bzr-nonadmin-1.11-1.exe) and extracted the files. Afterwards the bin/ directory has been added to the path environment variable.

The next step was to create a repository by running 'bzr init .'. Everything works up to that step. But when I try to add a new file to the repository using 'bzr add test', I get the following error.
  ERROR: File does not exist u'c:/est'.

C:\test is currently an expample. If the file is not located within the root of the drive, the first character of the path is removed, e.g. 'c:/ath/to/file' instead of 'c:/path/to/file'.

If I run 'bzr add jtest', the file named 'test' is added successfully and committing changes is possible.

The system is Windows XP Service Pack 3.
