Title:
  strace crash

Status in strace package in Ubuntu:
  New

Bug description:
  Binary package hint: strace

  Crashed while tracing python. The traced program didn't stop though, but finished happily...
  It was repeatable and I managed to minimize it thusly, with unpacked moin 1.8.2 tarball:

  erno at hat:~/src/moin-1.8.2$ strace python -c 'from MoinMoin.request.request_cli import Request as RequestCLI'
  [much output]
  open("MoinMoin/events/MoinMoin.pyc", O_RDONLY) = -1 ENOENT (No such file or directory)
  open("MoinMoin/events", O_RDONLY|O_NONBLOCK|O_DIRECTORY|O_CLOEXEC) = 7
  fstat(7, {st_mode=S_IFDIR|S_ISGID|0755, st_size=4096, ...}) = 0
  getdents(7, Segmentation fault (core dumped)

  Doesn't crash without strace.
