Compliled a simple program for testing the debugger.

int main(int argc, char **argv)
{
    int i;
    for(i=0;i<10;i++)
        puts("Hello World!);
    return 0;
}

(1)From the debugger console on the bottom of geany I set the target for the debugger to the sample program binary.
(2) I hit the start button to start debugging.
(3) After the debugger executes the program I hit stop.
Geany Crashes and takes the desktop environment down with it putting me back at the login screen.

(gdb) run -v
Starting program: /usr/bin/geany -v

The debugger is a plugin, plugins have their own bug list here: https://sourceforge.net/p/geany-plugins/bugs/

Also 0.21 is several versions old, you could try an newer version. I believe there is a PPA for Ubuntu with the latest release.

The fact that the whole desktop crashes suggests its actually a problem in the modifications Ubuntu made to the graphics stack to support Unity, its a well known problem that the menu stealing has bugs.

Ticket moved from /p/geany/bugs/1046/

Can't be converted:

• _found_in: v0.21
• _milestone: None

[Colomban Wendling]

As @elextr mentioned, version 0.21 is quite old, please try with a newer version. Also some crasher bugs were fixed or in the way to be fixed in the current development version, so you might want to try that.
