I download and compile qt 4.8beta1 some days ago.

My main task is checking the "heap snapshot" in web inspector to help me resolve problem of mem-leak.

but I find some problem:
1. in default case , the "heap snapshot" can't be found in profile tab of web inspector
2. I modify settings.js to enable heap snapshot then re-compile qtwebkit, this time , I can find "heap snapshot" but the feature can't work. as follows:
    a) click "take snap shot" , no more response happened, or nothing happened.
    b) input "leakz" , enable detail mode; then click "take snap shot" , as attachment 1.png, but no more response.
       this time , I capture the console info for above b step. as attachment 2.png to help resolve problem



attachment 1.zip contains 2 files 1.png and 2.png .
