We have not heard of this before but it seems likely that the problem
is due to attempting to close a file descriptor which is not currently
open (either never been opened, or already been closed). This could
be due to a bug in libtiff or your application.
You are going to need to debug this for yourself some more such as
finding the call stack and arguments which lead to this situation.
