I'm assuming she didn't make her script immutable and then forget to mention it. But who knows? If we can't figure it out from her replies to our *many* requests for additional information, then my next request would be to strace it, and see exactly which system call is failing. Either that, or someone else running sid might speak up and confirm whether they can reproduce the result.
