Comment (by vorner):

 Hello

 Replying to [comment:1 jreed]:

 system.

 No. This is the exit code/return status/$? of the process. That has
 nothing to do with errno codes. I wrote a small program to decode the
 value, assuming that ubuntu doesn't have different status encoding from
 gentoo:

 {{{#!C
 #include <sys/types.h>
 #include <sys/wait.h>
 #include <stdio.h>

 int main(int argc, const char ** argv) {
         printf("Exited: %d, Exit status: %d, Signaled: %d, Signal: %d\n",
                         WIFEXITED(11), WEXITSTATUS(11),
                         WIFSIGNALED(11), WTERMSIG(11));
         return 0;
 }
 }}}

 The output is:
 Exited: 0, Exit status: 0, Signaled: 1, Signal: 11

 So, the problem is SEGFAULT somewhere in the code. We might want to add
 the decoding of the exit code into the boss sometime, the number is not
 really helpful.

 Jaspain, would it be too much to ask if you happen to have core dumps
 enabled? A backtrace from gdb could be very helpful (KDE has a really
 useful thingie, if a program crashes, it tries to get the backtrace
 automatically and detects if it could be useful and asks the user to send
 it, we probably want to think about some simple way for this as well).

 Thank you
