Honzo? Thanks.
Comment 3 Jan Stola 2015-09-15 11:51:56 UTC 
This exception can occur when Bower is not configured correctly. If this happens then we may not be able to get information about installed Bower packages. If this happens then the project properties UI correctly informs the user about this problem. Unfortunately, if the user doesn't fix the problem and doesn't reload the list but presses OK button instead then this exception occurs.

I have modified the corresponding code to avoid the exception in the described scenario.
