It is quite reasonable for that to happen for a single user encountering
the error. Other users who do not encounter an error will keep working.

The unfortunate victim can always click the back button on the browser
to see earlier pages.

If you have your logging established to email errors to you or your dev
team you will see what is happening and be able to repair the damage.

That is the way to discover exactly where to put your try/except blocks
or more rigorous checking.
