RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Fixed In Version: poppler-0.12.4-8.el6
Doc Type: Bug Fix
Doc Text:
pdftops now generates valid PostScript files Previously, the pdftops utility of Poppler converted PDF files with embedded PostScript Type 1 fonts in the Printer Font Binary (PFB) format together with the PFB headers. As a consequence, incorrect PostScript files were produced from such conversions. Poppler has been fixed to recognize the PFB headers and exclude them from the conversion, and the described problem no longer occurs.

    GPL Ghostscript 9.15: Unrecoverable error, exit code 1


Version-Release number of selected component (if applicable):
poppler-utils-0.12.4-3.el6_0.1.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. Download attached pdf file
2. Execute '/usr/bin/pdftops 20-200002-001.PDF'
3. Open file using ghostscript 'gs 20-200002-001.ps'

Actual results:
ghostscript exits due to unrecoverable error

Expected results:
ghostscript should show .ps file

Additional info:
This error is not reproducible if ghostscript is used as backend (instead of poppler) to generate .ps file.
Comment 2 Marek Kašík 2015-06-24 12:54:58 UTC 
The problem here is that the Type1 font embedded in the PDF is in PFB format and includes PFB headers which are not removed before embedding the font again to the resulting PostScript file.

I've prepared a patch which fixes the problem for me and attached it here:

https://bugs.freedesktop.org/show_bug.cgi?id=19747

I would like to have upstream's opinion on the patch so I'll wait with devel_ack.
Comment 3 Marek Kašík 2015-07-09 09:33:03 UTC 
The patch was accepted by upstream so I'm giving this bug devel_ack+.
