Hi,

I have written a small python app that uses the pyexiv2 library.  However, when 
running the app, I see an interesting behavior.

My app walks through a directory and its subfolders, renaming each file 
according to it exif data metadata.  It also writes the old filename to the xmp 
metadata fields as keywords.  The at first the app functions normally, memory 
usage is under control, the processor barely being used and near constant file 
I/O.  However, it came to a point where memory usage climbs, processor is maxed 
at 50% (only using one core). and disk I/O is very sporadic.

I get error messages to the console such as the below....

Warning: Directory NikonPreview, entry
0x0201: Data area exceeds data buffer, ignoring it.

I am wondering what might be causing this.  I cannot reproduce the error or the 
conditions using the exiv2 binary for windows.  It seems to read all the 
metadata without errors.  So I am not sure whether this is a bug in exiv2 or 
pyexiv2.

-Please Help
