1507065 – PyGIWarning while running system-config-printer

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 Dan E 2017-10-27 14:50:53 UTC

Description of problem:
While trying to setup a printer. I use the system-config-printer command.
Until about three weeks ago, I started seeing this issue:

$ system-config-printer
/usr/share/system-config-printer/system-config-printer.py:30: PyGIWarning: GdkPixbuf was imported without specifying a version first. Use gi.require_version('GdkPixbuf', '2.0') before import to ensure that the right version gets loaded.
  from gi.repository import GdkPixbuf
Floating exception
$ 

Version-Release number of selected component (if applicable):
$ yum list system-config-printer
Loaded plugins: amazon-id, rhui-lb, search-disabled-repos
Installed Packages
system-config-printer.x86_64                            1.4.1-19.el7                            @prod-base
$ 

How reproducible:
Type the command: system-config-printer

Steps to Reproduce:
1. type the command: system-config-printer
2.
3.

Actual results:


Expected results:


Additional info:
I noticed this or a very similar issue has been fixed in Fedora 25. I'd like a to know if a fix can be implemented for RH 7.4 +

https://bugzilla.redhat.com/show_bug.cgi?id=1354606

It’s a Fedora fix, but somehow it was tagged as a Duplicate (of a red hat issue) here:

Comment 3 Ajinkya Patil 2017-12-04 19:36:20 UTC

Greetings,

Is there any workaround for this?
When can we expect a fix?

Comment 21 Zdenek Dohnal 2018-01-22 09:15:04 UTC

system-config-abrt behaves the same like system-config-printer (its start ends with floating point exception), so the issue (bug or only misconfiguration) is clearly not with s-c-p.

path to avoid pigiwarning

there is patch fixing warnings comes from gdk. It was tested on rhel75 on x86_64

Please don't miss this patch with crash of ssh - It is different issue, which should be tracked in different bugzilla.

Comment 24 Steve Bonds 2018-10-31 20:12:03 UTC

Here's a quick fix by including the newly required extra gi.require_version lines:

Comment 25 Zdenek Dohnal 2018-11-05 09:54:26 UTC

Hi Steve,

thank you for the patch! Actually Petr already created the patch for PyGi warnings which were shown in Dan's case, but I can verify other warnings show up and your patch fixes them. Thank you!

Comment 30 Steve Bonds 2019-07-17 13:26:42 UTC

I see that a TestCaseNeeded flag was added. It seems like we have a fairly simple manual bug-reproduction process. What additional info is needed to create a test case?

This means that automated / manual test case in our internal tooling needs to be created as part of fixing this bug.

Comment 32 Steve Bonds 2019-07-17 15:20:40 UTC

Got it. Since that is "internal tooling" there doesn't seem to be much people from the world at large can do from an Open Source point of view. Is that correct?
