I am not an expert but after researching a bit, it seems to be a problem with 
OSX itself.
There are issues relating reading local PAC file on OSX

Hope this would help,

Hi all,
This is a bug that I have recently fixed. It happens if no PAC file is there 
but still settings for a "whitelist" exist then this settings are applied on a 
null selector and this causes the exception. This issue is fixed now in the 
source code repository.
Please checkout the latest version from the source as I can no longer upload 
binary release files to google code.

Thanks for reporting this,
