[New-bugs-announce] [issue7639] bdist_msi fails on files with long names

[Mikhail Terekhov]

New submission from Mikhail Terekhov <termim at gmail.com>:

When I try to build msi installer for my module that contains files with long names it crashes with the following traceback

C:\home\python\dist_msi_bug>python setup.py bdist_msi

It seems that Directory.make_short fails to create unique short names in some cases. The test files are attached.
