On start of asp.net mvc 4 application getting ambiguous exception- Index and length must refer to a location within the string. Parameter name: length

Here's the stack trace. 

[ArgumentOutOfRangeException: Index and length must refer to a location within the     string.
Parameter name: length]

Is there any way to find out where this exception is coming from other than throwing random breakpoints everywhere? Thanks!

I ran into the same issue and was able to resolve it.

It turns out that at some point I fat-fingered something while in Global.asax.cs. I ended up changing the method Application_Error to Application_ (with a new line after it, stupid wide fingers...). This is what was causing the error to appear for me. Rewriting it as Application_Error resolved the issue.
