[Mono-docs-list] monodoc --edit crashes on newly created doc

[Matthew Pirocchi]

I'm working on following this guide to getting started on documenting my
code:
http://www.mono-project.com/Generating_Documentation

My code is divided into 4 assemblies, so I generated the documentation with
these 4 commands:

mdoc update -o cardinal-doc Cardinal.exe
mdoc update -o cardinal-doc Cardinal.Core.dll
mdoc update -o cardinal-doc Cardinal.Interface.dll
mdoc update -o cardinal-doc Cardinal.Services.dll

This created a folder named cardinal-doc with the xml documentation, as
expected. I now want to edit the documentation using monodoc, so I used this
command:

monodoc --edit cardinal-doc

MonoDoc opens, and I see "Cardinal" in the sidebar as expected. I can click
on "Cardinal", but when I expand it and try to click on any of its
assemblies, monodoc crashes with this trace:

Any idea what's going on?
