Use a debugger to get the backtrace when the application crashes.

thanks for replying first..
in my application if the user clicks the button animate the program animate.exe i start it with QProcess so when i click the button animate the QProcess starts the program and within 1 sec of timeout it will embed the program .. here on clicking animate seg.fault arrives but only for the first time i running next time it embeds perfectly ....

It could still be any kind of programming error. It makes no sense to try to guess what could be the problem. Using a debugger will much more likely reveal the problem.
