I think I know where the problem is :
I tried my application on the phone with the latest stable version of qt 
libs (4.5.3~git20090723-0maemo4+0m5). It didn't crash at all !!!!
the problem occuered when using the test version of qt 4.5.3 libs 
(4.5.3~git20090723-0maemo4.2 ) which I found here: 
http://qt4.garage.maemo.org/fremantle.html
I got to the url with my phone browser, and installed the packages. I 
turns out that the testing version of libqt4-webkit crashes with some 
urls (like MY_URL unfortenately and google.com !!). also mentioned here 
: http://discussion.forum.nokia.com/forum/showthread.php?t=186486

So, I guess the best thing to do is to stick with the stable libs And 
just wait for the new ones to get stable!!!

thanx very much for your help!
