Unfortunately, I'm running into the exact same problem. Konsole isn't crashing, it is terminating normally. "Error opening terminal: unknown." is printed to the console, and then exit is called.

I first ran into this bug attempting to fix an unrelated bug on another project (which I had not run with Kdevelop before). Due to unloading issues, the program segfaulted instead of closing cleanly, so I am unable to see the error given.

When I created the "hello world" ncurses program in an attempt to debug this problem, konsole immediately closed after stepping past initscr.

I am using the separate I/O terminal. It is Konsole. The bug occurs when using KDE, as well as xfce and Gnome. Konsole works normally aside from this bug.

+++ This bug was initially created as a clone of Bug #59276 +++

Version:           3.0.0a4 (using KDE KDE 3.1.2)
Installed from:    Debian testing/unstable Packages
Compiler:          gcc 3.3 linux 2.4.21-rc1
OS:          Linux

I want to debug a application using the ncurses library.
But the debugger crashes during the initscr() call.

For example...

#include <iostream>
#include <cstdlib>

#include <ncurses.h>

int main(int argc, char *argv[])
{
  initscr();
  endwin();
  printf("quit\n");
  return EXIT_SUCCESS;
}


I set a breakpoint at initscr() and when i step over this line the debugged terminal crashes immediately.
I'm using the seperate IO Terminal.

When i call the whole thing from the shell with the same gdb-calls it works fine.

Debugging Shell is /usr/bin/libtool.

Debbugger output:

... and here i hit step over and my test-app crashes.
