Bug 1009361

I've seen this exception from time to time also in previous versions of installer. NPE is thrown, however it will not affect installation in any negative manner and I am able to successfully complete it (but golder rule says : It's never good to get NPE :)).

There isn't any reliable way to reproduce this as it just occurs from time to time.

Here is stack trace:
