I can't reproduce your symptoms on 9.10. For me, the original problem
is fixed; I no longer see the strace output I quoted above. Your need
to chdir away from your home directory is probably pertinent. I'd
suggest investigating that and perhaps using strace -p pid-of-bash -s
3000 -f -o /tmp/st
I can still reproduce this bug with Ubuntu-9.10 Karmic (tested in a xterm).
It happens rarely but I managed to reproduce it at least twice.
I happens more often if I run it strace.
I ran...
$ strace -s 3000 -f -o /tmp/trace-xterm xterm
And in the xterm, I ran the non existing command:
$
I agree, it does look as if it still fails in a similar manner in the
case you strace'd. Perhaps the fix above works, but there's a race
condition where the checks don't always work.

Anyone reading this? Should I open a new bug? (Not sure about the
correct policy for bugs that are already marked as resolved.)
Anyway, an update: the fix in comment #6 of

No, it isn't specifically to do with Python. See my comment above where
read(2) on stdin returns EIO; I think that's a route to tracking it
down.

We created own implementation of command-not-found for SUSE and have the
same problem. So it is not Ubuntu specific, but it is broken somewhere
between command-not-found handler and python script.

I get this with Hardy too. I strace'd the bash running in another

I still observe this bug after upgrade to Hardy.

I can also reproduce this bug fairly easily after a couple of tries on
my feisty laptop.
I tried to run bash within valgrind memory checker and it detects
several errors:
I run a bash with:
$ valgrind --trace-children=yes bash
... then try to run a non existing command in background and get
Bash is not using python but python is invoked from bash's
command_not_found handler (command-not-found is obviously implemented in
python). This may be a python issue of some sort but is still does not
explain why bash is exiting.
