Ionic.Zip.BadReadException Could not read block Error

[Callistus Schissel]

Calling IWebDriver driver = new FirefoxDriver();
from a Console Application DotNet works fine...

Calling FirefoxDriver from compile Class Library doesn't work. In the
C:\Users\callistus.schissel\AppData\Local\Temp\1 it
creates the webdriver.xpi directory and anoonymous@@@.webdriver-
profile but doesn't unzip any information into the a
weddriver.xpi directory.

I am using version selenium-dotnet-2.0rc3.
