Dunno if I tried that correctly - probably not:

| Reading symbols from emacs...
| SIGINT is used by the debugger.
| Are you sure you want to change it? (y or n) [answered Y; input not from 
termin\
| al]
| DISPLAY = :0
| TERM = dumb
| Breakpoint 2 at 0x18d028: file xterm.c, line 24407.
| (gdb) run
| Starting program: /home/micha/software/emacs/src/emacs
| During startup program terminated with signal SIGSEGV, Segmentation fault.
| (gdb) xbacktrace
| You can't do that without a process to debug.
| (gdb) bt
| No stack.
| (gdb)

I always get "During startup program terminated" not matter how long I
wait.

In the second window I got this:

but that is probably not different from what I had posted initially.
