I see the (managed) exception in various situations, firstly seen in my
PropertyGrid WinForms exercising app, in a conversion of an accessibility test
app
(http://lists.ximian.com/pipermail/mono-devel-list/2008-August/028895.html), in
IEClone, etc.

A very simple repro app is included below.  Run it and hit <Go>.


Tested only on Windows 2.0 preview (mono-2.0-gtksharp-2.10.4-win32-2.exe).  I
don't have a working Linux 2.0 build or install.  That app works on 1.9 Linux
and Windows.

The following exception occurs -- the URI in it is garbage.  So there are
possibly two bugs, firstly that this exception occurs, and secondly that
garbage strings can be created.

[[
System.UriFormatException: Invalid URI: The format of the URI could not be
determined:
