Could you describe the steps leading to this message, preferably in the form of a unit test?

It looks like a bug in your MANIFEST.in to me, but we need a test to be sure. At worst it’s a bug in distutils, at best it needs a better error message.

Repro steps on a Windows machine:

1. pip install --no-install django-navbar==0.2

Yes, it seems like a bug in the MANIFEST file of the django-navbar project (which is not mine) that seems to have been fixed in the subsequent 0.3 release.

> at best it needs a better error message.

There is a simple way to fix this: change one line in sdist to catch ValueErrors in addition to DistutilsTemplateError.  Users will get a on-line warning message with the ill-formed manifest line number instead of a wall of traceback.

This is clearly a bug fix IMO: it is documented that distutils code can raise standard exceptions in addition to Distutils* errors, so here it’s not a new feature but a fix for sdist.

(Another way to fix this, would be to catch ValueError raised by convert_path in filelist and wrap it in a DistutilsTemplateError, but I’m not sure it really buys us anything.  Maybe it would be the better fix for Packaging, where the Manifest class is intended for public use.)

a one-line*

I’ll have a patch up for review shortly.
