Hi Susan,
I'm not sure if the problem we were having is related to yours since
you're dealing with .jpg files (we have all .pdfs), but we saw lots of similar
errors prior to switching from the use of PDFBox to xpdftotext and
xpdftothumbnail. When we were using PDFBox, approximately 10% of the documents
in our repository would not filter due to errors that looked suspiciously like
the ones you're getting. Now that we've switched to xpdf, 100% of our
documents filter successfully.

Subject: Re: [Dspace-tech] media filter problem
Hi all,
Just wondering if anyone else is having this issue - I haven't seen
other comments, which leads me to believe it's either a) a bug or b) our
installation.
Thanks for your help!
Susan
