Hi Jan, Could you install the debug-infos so we can get statement numbers? I assume this is reproducible and likely has something to do with the contents of the directory. So, perhaps you could send me (i.e. not post) the ls -LR of the stuff you are trying to copy. Andy

We have tried reproduce this and were unable to do so. Since we moved onto several releases ahead, I am closing this. Should tis happen again, please create a new ticket.
