No wonder it doesn't work - your "xml file" is not well formed, only
contains XML declaration.
Also your repro code should be applied one liner fix that makes it very
much helpful by *not* overwriting the same file which makes it
impossible to examine the issue. You could just save XML into *another*
file, so that everyone does not have to re-extract your archive over and
over again.

I've narrowed the issue down - it only occurs when XDocument.Load is
used with LoadOptions.PreserveWhitespace. I've uploaded an example
demonstrating this error. The relevant XML file is in /bin/Debug.

I have one doubt that I think is likely the cause of the problem and
also that prevents me from verifying it: you seem to have non-ASCII
character in your XML you pasted in the message. This could be cause
of the error e.g. inconsistent encoding input/output. A reproducible
test case that everyone can examine is appreciated.

I can duplicate this problem on Linux Mint 12 and Ubuntu 11.10, but
Microsoft.NET on Windows 7 does not have the issue. The issue is
that my XDocument becomes corrupted the moment it loads, and cannot
be saved. Strangely, I am able to traverse it and manipulate it in
memory. The following code:
Stream s = File.Open("example.xml", FileMode.Open);
XDocument d = XDocument.Load(s);
s.Close();
d.Save("example.xml");
Produces the following exception:
[23:19:05] PartyCraft.CurrentDomain_UnhandledException: Error:

The same exception occurs on d.ToString();
The XML that is being loaded looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<partyCraft>
<server maxplayers="100">
<motd>PartyCraft Test Server</motd>
<messages>
<death>
<!--TODO-->
<suicide>§e{0} killed themselves.</suicide>
<creeper>§e{0} looked at a creeper funny.</creeper>

<command>
<alias>
<setting>s</setting>
</alias>
</command>
<plugins>
<!--TODO-->
<plugin>TestPlugin.dll</plugin>
</plugins>
</partyCraft>
And when saved, even though an exception occurs, the document is
overwritten with this:
<?xml version="1.0" encoding="utf-8" ?>
This is the output from mono --version:
