.git shortening does not work properly

The .git command does not shorten urls properly(how ever converting a short url to the full url works as expected) it results in the following message from the bot:

01:05:51 AM .git https://github.com/xxxxx/xxxxxxx/commit/xxxxxxxxx 01:05:52 AM <%gonzobot> (xxxxxxxxx) [HTTP 200] <!DOCTYPE html> git.io <!--[if (gte IE 6)

Actual url masked for privacy reasons

The console provides the following message:
