Try This
1. As you already did run ./buid-webkit --debug --qt
2. cd WEBKIT_DIR/WebKitBuild/Debug/bin
3. Assuming you have WEBKIT_DIR/WebCore , WEBKIT_DIR/WebKit source
    $ gdb -cd . -d ../../../ --args ./QtLauncher <args-to-QtLauncher>
4. Now at gdb prompt
    (gdb) break main # to add breakpoint to main function
    (gdb) break WebCore::FrameLoader::init # make sure you use
fully-qualified namespace

1. same as above
2. same as above
3. Create a text file with gdb commands
$ cat <<EOF > commands.txt
            break main
            break WebCore::FrameLoader::init

4. run gdb as
$ gdb -x comands.txt -d ../../../ -cd . --args ./QtLauncher

Qt comes with (std distribution) with gdb 6.8 or something, if you gdb 7.01
or above
you will be able to leverage some of the python gdb scripts distributed with
