Title: Fix OpenEXR brittleness with malformed metadata.

Our particular case was a string called "tiles" -- triggers an exception inside libIlmImf.

I suppress this particular case by name, but also to avoid this kind of problem in the future, I enclose a whole section of put_parameter in a try/catch block, to deal with other unanticipated OpenEXR exceptions when setting attributes.
