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:

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:

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?
