Stopping

Other information:
My hard disk recently crashed so I'm trying to re-import my photographs into F-Spot.  I have an existing F-Spot photograph hierarchy on a backup drive that I'm trying to copy into my new RAID array.

After importing a few hundred RAWs, F-Spot logs the above exceptions.  Depending on how many files are attempted to be imported, F-Spot will report the error however it may or may not segfault.  Also with too many file handles leaked, icons and thumbnails may render as the default error or ? icon.
