Fatal Error when adding metadata and covers.

[jgforbes]

When adding metadata and covers for multiple books I am getting the error below and it
cause calibre to hang and requires kill -9 to remove. The offending directory has no cover or book in it. The files are on a file server accesses via CIFS and I think that there may be
some issue with file access. Nevertheless, this error is not being handled gracefully.
