Applications Start Page Profile Option Causing Issues

Question

Hello Oracle Gurus,
I'm having an issue in a 12.1.3 instance that I think may be related to the "Applications Start Page" profile option.
For testing purposes, we set the profile to a specific Self-Service page at the Site level. We eventually removed the Site level profile and added it at the user level just for specific users, but since the Site-level profile was set, every time we click the Home link in the upper right-hand navigation, we get an "unexpected error." If we attempt to log in as a user that does not have the Applications Start Page profile defined, we also get an unexpected error.
After getting the error using either of the methods listed above, if we then try to navigate back to the login page, the instance throws a 500 Internal Error.
If we close the browser and navigate to the instance again, we're able to log in without any issues with user accounts that have an Applications Start Page profile defined.
Our "Self Service Personal Framework Mode" is set to "Framework Only" at the site level.
Bouncing Apache seems to resolve the issue temporarily, but then it comes back again a few hours later...
We've opened a Service Request, but has anyone else run into this before / have any ideas on how to fix it?
Here are some related Metalink notes from 11.5.10:
729375.1 (About the Applications Start Page profile option)
331814.1 (Error on Personal Home Page when returning to 'Home' link)
Thanks!

The issue is not specific to a responsibility or application.
Here is the error:
Fatal NI connect error 12170.
