When I'm trying to rebuild my examine index I get the following error:

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Source Error:
The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:
1. Add a "Debug=true" directive at the top of the file that generated the error. Example:
<%@ Page Language="C#" Debug="true" %>
or:
2) Add the following section to the configuration file of your application:
<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>
Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.
Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

Yes I'm using DAMP on the node that throws the exception and I'm also using Embedded Content on some other nodes. Do you have any idea what might be the problem?
I've seen this before where Examine chooses to index XML nodes that aren't Umbraco XML nodes, but I haven't gone deeper into it to work it out. It might be something different in your case, but I'll have a look to see if I can reproduce it locally.
I dug into this a bit further: for me this error occurs if there is a non-umbraco node in the content XML that has an "id" attribute.
I had it occur when DAMP included the Embedded Content XML from a media node in RLZ (though it could equally occur if the Embedded Content field was included directly).
If this does describe your problem, the patch below seems to fix it. I'll submit this once I've prettied up the test case. The patch is against Examine 1.0 RTM: if you want the binary I can email it to you.

Jeroen
It happens when I try to rebuild the InternalIndexer. Other indexes work.
Jeroen
Are you by any chance using DAMP or Embedded Content - or both?
Yes I'm using DAMP on the node that throws the exception and I'm also using Embedded Content on some other nodes. Do you have any idea what might be the problem?
Jeroen
What umbraco version?
Can you put a link to the XML file for your site?
I've seen this before where Examine chooses to index XML nodes that aren't Umbraco XML nodes, but I haven't gone deeper into it to work it out. It might be something different in your case, but I'll have a look to see if I can reproduce it locally.

I'm facing the same issue. Any chance you could send me the binary james :) mskiltonATgmail.com... thanks...

THANKS!
I just tested the 1.1 beta and it's solved! Many thanks.
Jeroen
Looks good to me :)
thanks guys. just waiting on feedback from a few others and will release.
@Shannon: what are the chances of the updated Examine release making it into the 4.7 umbraco release? I'm guessing pretty slim, right?
That's not going to happen. Just got a twitter message from Niels Hartvig.
Jeroen
I'm running 1.1 on a couple of live sites and its working fine for me.
is working on a reply...
