    NPE is not a rare error so you have to contact the author and ask what the fix is.

    This exception means that the application is trying to access an object that no longer exists. Looks like the app needs to be rewritten.

    As both ken_yap and imterpsfan2 said it's most likely a problem that the author can solve.
    What I wanted to add is that it also could be caused by wrong usages of the program.
    Although the application should never assume he gets a parameter it sometimes does.

    Try to read the documentation and see if the program is expecting a parameter.

    Best of luck!

    dir -R /home/* | grep "coffee cup"
