Exception thrown when parsing appointment with comments from the composite feed

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a new appointment in GCalendar and add a comment to it with the
"Add a comment" link.
2. Try to get the appointment from Google Calendar .NET API using the
composite feed.

What is the expected output? What do you see instead?
The expected output is an EventEntry object representing the appointment. I
get an exception instead. The stack trace follows:

What version of the product are you using? On what operating system?
1.2.0.0

Please provide any additional information below.
This only happens when the appointment has comments. Inspecting the
composite feed, I see the comment is represented with an <entry> tag.
Inside is an <id> tag that contains what seems to be an identifier (but
it't not an URI). Maybe this string is being used to initialize an URI
raising the exception.

Fixed in subversion. Will be in all versions > 1.2.1.0

Note there seems to be a service side issue with UTF8 encoding of non US 
characters, i found some composite 
feeds that failed to parse due to that, just in case you are running into that 
as well. We are investigating that.

Yep, I noticed that and reported the bug at gdata-issues a couple weeks ago.
