What version of the product are you using? On what operating system?
Elmah v=1.2.2(NuGet), v=1.2.14706.0(properties in solution explorer); Windows 7

----------------------------------------------------------

Please provide any additional information below.
View in XML looks fine.

I think the problem occurs because JSON can’t create an ‘empty’ key.
XML part that I think causes the error for JSON:
<queryString>
<item name="">
<value string="fb_xd_fragment"/>
<value string=""/>
</item>
</queryString>
Rest of the view in XML looks fine.
And query string is: "(...)default.aspx?fb_xd_fragment&"

Could you elaborate on the steps to reproduce this bug? I'm not sure what you 
mean.

@thomasardal: I think I understand what the problem might be. If the error is 
logged during an HTTP request where the query string portion in the URL has an 
unnamed key (e.g. http://www.example.com/foo?bar) then recalling the JSON for 
that error breaks.

@thomasardal: I just tried and managed to reproduce the issue. Assuming a 
domain like www.example.com and ELMAH handler configured at /elmah.axd, log a 
test error using the URL http://www.example.com/elmah.axd/test?foo. The bug can 
then be provoked by visiting the error log page, going to the detail page of 
the logged error and asking for the JSON format.
