We have some code in a managed package that allows a user to preview a Visualforce PDF, and once they are satisfied, they can save the file back to the parent record. This code works fine when the Visualforce page called is in our managed package. However, if the managed package instead tries to call a Visualforce page outside of our managed package, then the page crashes with a WSOD (White Screen of Death).

The error is as follows:

An internal server error has occurred

Of course, I've submitted a case to Support, but I wanted to see if anyone has encountered a problem with getContent() crashing a Visualforce page like this, and what the resolution to this was.
