So I upgraded to 1.9.6 RC1 and I'm having a sporadic problem. Some times when

I try to enter users in the admin panel I run into the 2 errors below (from yaf's logs).

Other times, I can enter the users panel just fine. Any ideas?

.Net SqlClient Data Provider

Invalid column name 'Birthday'.

Invalid column name 'Birthday'.

Invalid column name 'Birthday'.

ASP.default_aspx

System.ArgumentOutOfRangeException: The added or subtracted value results in an un-representable DateTime.

Parameter name: t

I try to enter the users tab. Odd thing is, if I restart the app pool (restart the app/save web_config) the problem

goes away for a little while. The solution is only temporary though, an hour or two later I can't enter the users

page in the admin panel again. (See error below)

It seems that it's connected with URL rewriting logic.

After a little more research this error only seems to occur when I have logged into the forum from two seperate computers. If I only use one computer the error doesn't appear, as soon as I log in on another pc it starts again.

Looks like this was a very rare issue, but i was able to reproduce it. It should be fixed now in the repository.

Something horrible detected again in the latest repository on the front page.

I see the same db calls with or without rewriting enabled. The user_list sp calls come from the UserLink

string displayName = this.Get<IUserDisplayName>().GetName(this.UserID);
