Error when exporting iphoto library

I have a 66,000 pic iPhoto library that I have been exporting with Phoshare 
1.0.6 using the command line: 

/Applications/Phoshare.app/Contents/Resources/Phoshare.py -e . -d -k -u --size 
1920x1920^ --iphoto "~/Pictures/iPhoto Library" --export "~/Dropbox/iPhoto 
Backup"

Phoshare gets through about 6,000 photos and then presents the following error 
(consistently -- happens when rerunning Phoshare too...)

New file: /Users/dan/Dropbox/iPhoto 
Backup/08_06_2010/FacebookHomescreenImage.jpg (convert)

What version of the product are you using? On what operating system?

1.0.6 on OS X 10.6.4. 

Please provide any additional information below.

The photos that seem to be faulting it were taken on a Blackberry. Tilman, if 
you would like a copy of the folder of images, email me at dan@danwarnemail.com.
