I get MultipleObjectsReturned when trying to view any diff #554

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
*NOTE: Do not post confidential information in this bug report.*

What's the URL of the page containing the problem?
http://reviewboard.eng.vmware.com/r/36076/diff/#index_header (although
James didn't see this)

What steps will reproduce the problem?
1. I just open the page.  It happens 100% of the time.

What is the expected output? What do you see instead?

What operating system are you using? What browser?
A newly-installed XP 32-bit system with Firefox 3.0.1.  I tried to restart
Firefox but it didn't fix it.  Oddly enough, IE 7 is reading it correctly.

Please provide any additional information below.

I just found that this happens when I use IE 7 also.  But the weird thing is 
that it
only happens when I am logged in as myself.  If I am not logged in, I can view 
the
diff just fine.

Odd that I just got the e-mail for this, but I think we fixed this for you a 
few days
ago. Come bug me if I'm wrong (I fixed a handful of these when the server went 
down).

Yeah, you fixed it for me.  Thanks for the help.
