Comment 5 for bug 430301

Hi.
I wrote patch that should fix this bug. It checks the directory of path you specify, and I also changed return values of few functions in main.cpp so it is possible to return 1 on failure. You also get warning with more apt message.
I would like to ask for someone kind to review it, I am not sure about changes in main, if there was reason for the way return code was handled previosly
