I have found that this issue can be caused by a corrupted data type. Have a look at this Umbraco form post:

http://our.umbraco.org/forum/using/ui-questions/39103-Problem-with-Rich-Text-Editor-and-Inserting-Images

I found that when I went through my datatypes one at a time the 301 redirect was throwing an error. When I deleted this the Media picker in the RTE was showing again

I hope this helps.
