Double check what are the ownership/permissions on the file.
ls -las /usr/local/lib/python2.7/site-packages/Trac-0.12.2-py2.7.egg
Also check ALL directory permissions down to that point. Must be
readable/searchable to Apache user.
Also double check permissions on egg cache directory:
ls -las /srv/trac/.egg-cache
You might also try reinstall the Trac egg in case it is corrupt.
