[MonoDevelop] Trouble MonoDevelop to work reliably on Ubuntu - Is this just a buggy difficult to install tool?

[Aris J. Green]

I installed Mono 1.9 and MonoDevelop 1.0 on Ubuntu Hardy and can't seem
to get it to work well.  The IDE often crashes when closing a file
dialog and addins seem to be missing.  I also can't add a new add-in
repository without the IDE crashing.

Is there a basic list of what I need to install to get this thing to
work.  Do I need Mono 1.0 also?
