Public bug reported:
Binary package hint: strace
Maverick made a policy change so that attaching to processes is not
allowed by default. That's fine. However, it's a bit strange that
strace just exits 0 (with a message to stderr) when ptrace fails.
The manpage says
When using -p, the exit status of strace is zero unless there
was an unexpected error in doing the tracing.
and istm this is such a case.
