Source code of a small project that reproduces the issue

Description of Problem:
When iterating on all Properties.Settings.Default.PropertyValues, a crash can
occur when calling settingsProperty.PropertyValue set accessor.

Steps to reproduce the problem:
1. I store 2 string values in Settings.
2. I read the first one at startup to load all settings properties.
3. foreach settings properties, I assign it tto itself
   foreach(SettingsPropertyValue settingsProperty in
Properties.Settings.Default.PropertyValues)
      settingsProperty.PropertyValue = settingsProperty.PropertyValue;
3. I call Settings.Save()
4. I build, run and quit the quit app.
5. I remove the second setting property
6. I build, run and quit the quit app
7. Crash during assignement in the foreach loop

Actual Results:
Crash the second time (after change of the settings).

Expected Results:
No crash

How often does this happen? 
Always
