I had 40 errors related to MimeType not found and I saw the word NotesFile pop out at me in the backtrace. Knowing that this model deals with uploaded files that have various mime types, I went straight to the code for this NotesFile model and started debugging -- without reading a single detailed line of the backtrace.

I lost about 10 minutes proving there was no error in the code for this model.

Then I read the actual backtrace in detail and saw that the underlying cause was, in fact, due to the ZipFile model, which also dealt with uploaded files (albeit seldomly).

Lesson:

Look at the actual backtrace instead of guessing. It is always faster to go the correct error location from the get-go.
