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.

Description David Miller 2017-01-04 22:47:11 UTC 
Description of problem:

Evince will no longer display postscript files after the ghostscript-8.70-21.el6_8.1.x86_64 update. Evince gives the following error in the console

** (evince:14625): WARNING **: Error rendering thumbnail
invalidaccess -7

Version-Release number of selected component (if applicable):

ghostscript-8.70-21.el6_8.1

evince-2.28.2-19.el6

How reproducible:

happens to every .ps file I try to open.

Steps to Reproduce:
1. Launch evince either in command line or icon in GNOME.
2. open a postscript file with evince.

Actual results:

The evince window says loading...

Expected results:

Postscript file is displayed.

Comment 2 Rob Henderson 2017-01-09 16:06:22 UTC 
I am seeing the same problem as the OP on RHEL 6.8.  In addition, I am also able to reproduce it with ghostscript-9.07-20.el7_3.1.x86_64 on RHEL 7.3:

$ evince try.ps
II 1
invalidaccess -7
invalidaccess -7
invalidaccess -7

On RHEL 7.3 the evince window comes up but the display is blank.  With RHEL 6.8 I also see the "Loading..." message.

It doesn't seem to be specific to any particular ps/eps file since I have see the same behavior with several different ps files from various sources.  I *am* able to display the files by running ghostscript directly but just not with evince.
Comment 3 Tom G. Christensen 2017-01-12 09:56:00 UTC 
This was fixed upstream in June 2016:
http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=99e331527d541a8f01ad5455c4eb2aabd67281a6;hp=0d4644c003067fc14ca1db9c600dce420c06e6b1

I've verified that the upstream patch fixes the issue with evince on el6.

rhel7 gs_init.ps patch

I have also verified that this fixes it on rhel7.  An ever-so-slight modification of the referenced patch that works on rhel7 version of gs_init.ps is attached.

A slightly different modification of the referenced patch that works on CentOS 6 is attached.
Comment 18 Kent Engström 2017-02-02 16:41:53 UTC 
Concerning the doc text "caused *evince* to stop displaying contents of PostScript files": Another regression seems to be that "ps2epsi file.ps" stopped working (with ugly backtraces). If that too is fixed (a patch of "put" -> ".forceput" in gs_init.ps fixed it for me), maybe it should be mentioned? Or at least  something to the effect that the evince display problems were not the only problems.

I'm sorry, but I didn't understand exactly what you were saying.

Are you refering to any BZ already opened? Or is this something new you have encountered? And is it fixed by the patch for this BZ?

In case you have encountered a new bug, please, create a new bug report. We will then look at it and evaluate the options.

Thank you!

David

I think I discovered the same regression bug that is discussed in this bugzilla entry, and that is fixed by the patch in comment #5 here. I also believe this is the same regression that is discussed in bz#1411843 and bz#1411725.

I got a report from a user at our site that "ps2epsi" had stopped working when we updated to ghostscript-8.70-21.el6_8.1.x86_64. When I manually applied the patch from comment #5 here, "psepsi" worked again.

So, as far as I am concerned, the bug will be fixed if you release a package that contains the patch. I just tried to help you write a better text for the release notes, by pointing out that the fix here solves regressions for more programs than just evince. Nothing more, nothing less :-)

Actually, BZ #1411725 is de facto clone of this BZ for RHEL-7. However, the BZ #1411843 is much more complicated in that sense.

The patch in this BZ will fix the issue in BZ #1411843 only partially. After the fix, the conversion there will still not work, and most likely it never will be. I have discussed the issues about it already with upstream, and I will post my findings there soon.

Thank you for the information, Kent. It might be good to test this issue as well.

I understand now. However, unless we have this confirmed by our devel/QE engineers, we can't make such guarantees in BZ documentation. I'm sorry about that.
