Description PC LX 2010-05-28 20:55:48 UTC 
Application that crashed: kdevelop.bin
Version of the application: 4.0.0 (using KDevPlatform 1.0.0)
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.13-desktop-1mnb x86_64
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
I had just compiled a project application, and instructed Kdevelop4 to run it. After a few seconds I sent a TERM signal to the project application and Kdevelop4 crashed. Sometimes Kdevelop4 crashes, and sometimes it freezes.

How to reproduce:
- Open a project;
- Compile the project;
- Run the application;
- From a terminal send a TERM signal to the application.

Kdevelop4 will either crash or freeze after the steps above.

If I try to reproduce this with the following app:

#include <iostream>

int main(int argc, char **argv) {
    std::cout << "Hello, world!" << std::endl;
    sleep(100);
    return 0;
}


and then kill it:
killall -s TERM cmaketest

kdevelop just prints this:
*** Crashed with return code: 0 ***

and continues to work just fine. If you can reproduce this, tell us how.
