Comment 6 for bug 296903

You don't need to run yelp with any additional arguments. You just need to run:

G_SLICE=always-malloc G_DEBUG=gc-friendly valgrind -v --tool=memcheck --leak-check=full --num-callers=40 --log-file=valgrind.log yelp

Before you do this though, you will probably need to install some debugging symbols. The procedure for doing this is detailed in https://wiki.ubuntu.com/DebuggingProgramCrash. Please add the necessary repositories as detailed in this URL, then run the following to install the debugging symbols that I think you'll need:

sudo apt-get install yelp-dbgsym libc6-dbgsym libc6-i686-dbgsym libstdc++6-dbgsym xulrunner-1.9-dbgsym libgtk2.0-0-dbgsym libglib2.0-0-dbgsym
