I'm having an issue with psycopg2. This issue never presented under 2.4.5 until I tried to install 2.5. After noticing the issue I uninstalled (pip) and re-installed the old version. The issue then persisted. I then manually copied the old version out of another project's virtual environment to resolve the issue. Here is a traceback I get when using SQLAlchemy:

Here is a traceback from a Django app as well. Here the final cause is incorrect because if I replace the database backend the main issue "Reason: image not found" persists.

Was there some change in 2.4.5 that was pushed under the same version number? I'm using Postgres.app (http://postgresapp.com) on my system and haven't seen this issue before. pip install resolves cleanly, this issue only comes up when I try to connect to the database.
