How to run a bash script inside Python, but act as if it were being run from another directory?

Question

subprocess.call(["/home/blah/trunk/blah/run.sh", "/tmp/ad_xml", "/tmp/video_xml"])

I'm doing it. However, inside my run.sh, I have "relative" paths. So, I have to "cd" into this directory, and then run the shell script. How to do it?
