gitolite.conf - Write and rewind permissions (W+) are being lost everytime a git push occurs

At my company, we are adopting Redmine as the support tool for our software projects management. Since we were using git for SCM, I've installed and configured the Redmine git hosting plugin and gitolite, since its a plugin requirement.

In the plugin configuration, I selected to automatically create a new repo everytime a new project is created and it seems to work just fine. After the project creation, I configure the users who should have access to the repo and the desired permissions for them through the gitolite.conf file.

However, a weird problem is occurring: everytime a push some commits into the remote repo, the W+ permissions are lost., being my user only able to read access to the repo.

Some useful information (I hope) about my system configuration:

• Redmine 1.3.2 stable (MySql)
• Redmine Git Hosting Plugin 0.4.2
