ASPX Editing in MonoDevelop has a few issues.

1. Unable to type into certain buffers:
Code:
<%@ Control Language="C#" Inherits="Tuxtorial.EditStoryHelper" %>

<% for(var command in Model.ConsoleContent.Commands) {
	Response.Write(command);
	} %>

Error:
When I trigger autocompletion, it fails and any keystroke inside the text editor
provides the following stack trace:
System.ArgumentException: length

2. Code completion very very flaky.
Please notice the screenshot in the link. Trying to complete "for" does not
yield valid results.

More examples:
I type in "Consol". It still shows no matches. When I type "Console.", it shows
me all the options available. If I select the option for "WriteLine" I get
"Console.WriteLinee" (the extra e is present in the completion"). The next time
the same was attempted I got "Console.WriteLineel".

Many other items which are visible at the target point aren't populating the
completion menu. Still, the second level of completion works fine. For example,
"<%= Htm<C-Space>" shows no response, but "<%= Html.<C-Space>" shows the members
of HTML.


Environment:
This was tested with Mono 2.6.4, MD latest version from git, no extras/addins
built. All pidb files were deleted and MD was cleaned before this was tried.


Reproducible: Always
