I have just started getting NullReference exeptions from all the Document Type screens in the Umbraco v6.1.1:
NullReferenceException: Object reference not set to an instance of an object.]

I have installed FamFamFam icons, and initially everything worked initially. It seems that assigning a particular icon has caused this, although I couldn't which, maybe sitemap.png
Yes, that's how I resolved it too, but I'm concerned that it should be an issue in the first place. In a live environment I couldn't just restart the application pool as a solution :)
I ran into same error when trying to create my very first document type (exciting stuff!). Restarting IIS Express worked for me too. Im also running Web Matrix, so I restarted the website in that as well.

Any ideas?
I restarted IIS (or in my case, IIS Express) and it worked for me.

I just came across this error too, restarting IIS also fixed this for me.
(Umbraco 4.11.7) + FamFamFam icon package installed.
IIS 7.5 is the Web Server (IIS)
