Event Handlers in startup.py cause Revit to Crash

Wondering if others have seen this - where the event handlers in the startup.py file have been causing it to crash Revit

nope, not once

Event handlers are notorious for crashing Revit if they experience an unhandled exception.

except Exception as e:
    from pyrevit import forms
    forms.alert('Failed event handler ###! {}'.format(str(e)))
