Trinkit, Thinking Web Solutions

Been playing around with site definitions lately and came across the most random error. I had deployed a site definition solution to my test farm and then all of a sudden I couln't access central admin. The error was:

"Exception occurred. (Exception from HRESULT: 0x80020009 (DISP_E_EXCEPTION))".

 

This didn't mean much to me and google suggested that I rebuild my site collection. In the end I fonud that there was a problem with my WEBTEMP.xml file.

I Had added a site template configuration like this:

<Configuration ID="1" Title="Base Publishing Site (Hidden)" Hidden="True" />

Which looks ok to me and I have seen a few samples that.

 

The missing element was the ImageUrl. So what I should have is:

<Configuration ID="1" Title="Base Publishing Site (Hidden)" Hidden="True" ImageUrl="/_layouts/images/blankprev.png" />

 

I'm wondering if this is something that has changed since SP1. If you look in the SDK you can see that ImageUrl is specified as Optional (http://msdn.microsoft.com/en-us/library/ms476942.aspx).
