Is the standard output file being created and then is found to be empty or is it not being created at all?

If it isn't getting created at all, then there is something wrong with your command line.  If it is being created but is empty, then I would focus on the webkit program.  Things to think about:

Take a look at the constructed command line.  You didn't show us that in your email.
Is webkit designed to behave differently when writing to the terminal versus a file?
Is the output being buffered when redirected to a file versus to the terminal?
