Followed steps : Downloading sources at 0.3.1 Build egg with 'python setup.py bdist_egg' Copy .egg file to 'trac/plugin' folder Restart server.

Trac page displays this :

I can reproduce. The following patch seems to be needed:

Same problem. we are lost our trac repo.

Replying to anonymous:

Same problem. we are lost our trac repo.

Lost is unlikely the correct word. It's possible you are seeing an error on every page, which is a good reason to always test plugins on another Trac instance before installing them.

To fix the issue, just disable the plugin and restart the webserver. If you still have an error, delete the egg. If you continue to have trouble, please ask on the ​MailingList.

Ethan, if you'd prefer I can make a pull request in the GitHub repository for the patch in comment:1.

See also ​issue 1 for UserPicturesPlugin. Another solution is to just remove include_package_data in setup.py, which would allow MANIFEST.in to also be deleted.

I created a ​pull request, so closing this ticket as a duplicate.

[Ryan J Ollos]

Issue is fixed in GitHub repository.
