I think this has to do with a recent LaTeX update that changes the
handling of path names with non-ASCII characters and spaces. See

I suppose the documents are in a path that consists of such characters
(maybe your surname?). Does the error go away if you move the document
to a patch with ASCII characters only?


PS. We have a fix for this in the development version, but it is not
tested thoroughly yet.
