When opening this file: http://scripts.sil.org/cms/scripts/render_download.php?site_id=nrsi&format=file&media_id=xetex_bachotex2006_paper&filename=kew-bachotex-paper.pdf, both backends crash. Here is the error message: Error: Unknown character collection 'Adobe-Japan1' Segmentation fault (core dumped) Even if poppler cannot find the fonts not embedded in a document, it should not crash when opening.

The segmentation fault when opening the document had nothing to do with the error warning "Unknown character collection". In the meantime, I've updated fontconfig, pango and cairo to their lastest stable versions and the documents open fine (so the bug is no longer critical and the summary has to be updated).
With the latest CVS head this problem should be fixed. You need to install the poppler-data package in the same install prefix as poppler, and the poppler should automatically read in the required encoding tables.
