This is what I found on the Microsoft site. Only difference is that i have IE 7.
CAUSE
This problem occurs with Web site links that use long URL strings that are called from scripts. This problem occurs because the additional information that is associated with a Web site URL is not correctly stored in the Index.dat file. The Index.dat file maintains a reference to all the Web site URLs that you visit. When you click a Web site link in Internet Explorer, Internet Explorer updates the Internet Explorer history with the Web site URL information. Sometimes, Internet Explorer stores additional information that is associated with the URL in the Index.dat file. If this additional information is very long, you receive the error message.
Note The Index.dat file is located in the %userprofile%\Local Settings\History folder.
