I'm getting the following exception when I click on the share link for an individual profile. I'm using the latest version from NuGet, 2.0.1.
The Exception:
System.NullReferenceException: Object reference not set to an instance of an object.

The code:
I found what I think is the source of the null reference in the code here:
ClientTimings clientTimings = null;
if (clientTimingList.Count > 0)
{
clientTimings.Timings = clientTimingList;
}
Am I missing something, or is that always going to throw an exception when there are entries in the clientTimingList
?
Workarounds:
I thought maybe if I disabled batching, I wouldn't run the LoadInBatch function, but LoadIndividually has the same issue.
I looked for a way to disable client timings, but couldn't find a setting for it.
Maybe I could set a trigger in the database to delete the rows, but that seems a little extreme.
If I get the time, I'll get the code and submit a pull request. I wanted to make sure I wasn't missing anything obvious first.
