Unity 4.2.2 Crashes When Switching Target Platform to Android

Hi guys, I have upgraded recently from Unity 4.1.2f to Unity 4.2.2f. I'm running on Windows 8 64-bit with Android SDK Tools r21.

After the upgrade, whenever I switch my target platform to Android and try to do a build, Unity crashes. It crashes before starting the build process. The crash happens during the process of switching the project's assets to the Android target platform.

I had a look at the Editor.log file, I found it having some information related to the crash that happened. However, I don't understand why it crashed. Here's some of the contents:

Does any one have any clue why this is happening?

Help would be very appreciated :).
