           Summary: Null reference exception on Settings.Reload
           Product: Mono: Class Libraries
           Version: 1.9.0
          Platform: x86
        OS/Version: All
            Status: NEW

          Priority: P5 - None

ZIP file containing a CSPROJ with all needed files

When I call Properties.Settings.Default.Reload(), Mono crashes with the
following null exception:

Unhandled Exception: System.NullReferenceException: Object reference not set to
an instance of an object
  at System.Configuration.CustomizableFileSettingsProvider.Reset
(System.Configuration.SettingsContext context) [0x00000]
  at System.Configuration.LocalFileSettingsProvider.Reset
(System.Configuration.SettingsContext context) [0x00000]
  at System.Configuration.ApplicationSettingsBase.Reload () [0x00000]

I've encountered this problem in both Windows XP (32-bit) and the Mono-provided
openSUSE 10.3 image.  I've attached a test case that has a Settings file with a
single Bool value in it.  Clicking the button fires off a
Properties.Settings.Default.Reload(), which will crash the executable.  I've
attached the entire CSPROJ (Visual Studio 2005), since the Settings file is
needed to demonstrate the error.
