// when any component throws an exception.
// See http://community.sharpdevelop.net/forums/p/10928/35288.aspx
// Reproducible with a custom control that has a designer that crashes on unloading
// e.g. http://www.codeproject.com/KB/toolbars/WinFormsRibbon.aspx
// We work around this problem by unregistering the designer host manually.
