Error on collection top-level page when thumbnails turned on.

[Rene Ramos]

Hello,

I'm running DSpace 5.5 on Windows.

The following dspace.cfg directive is set:

org.dspace.app.mediafilter.ImageMagickThumbnailFilter.flatten = true

However, I when navigating to Collection main page for a collection consisting of PDF files, where thumbnails and text have been extracted using ImageMagick, I get a page error and the error chain below in dspace.log

I thought I was handling "flattened" PDF issue with the directive above, but there still seems to be a problem with the JPEG thumbnails for PDFs.

I appreciate any thoughts on this.
