Description Joachim Frieben 2019-04-28 19:30:14 UTC
Description of problem:
Using pango-view with backend ft2 in a current Fedora 29 Workstation installation fails because pango-view tries to launch the display utility from ImageMagick which has not been pulled in as a dependency.

Version-Release number of selected component (if applicable):
pango-1.42.4-2.fc29

How reproducible:
Always

Steps to Reproduce:
1. Launch GNOME session of a current Fedora 29 Workstation installation.
2. Run 'pango-view --backend=ft2 -t PANGO'.

Actual results:
Utility pango-view aborts with the error message:
 "pango-view: When running ImageMagick 'display' command: Failed to execute child process “display” (No such file or directory)"

Expected results:
Utility pango-view displays the sample text.

Additional info:
- Installing package ImageMagick prior to running pango-view ensures correct execution. Therefore, adding ImageMagick as a requirement of package pango solves this issue.
- It is probably preferable to patch pango-view such that it calls "gm display" from package GraphicsMagick and to pull in the latter instead of ImageMagick.

Comment 1 Peng Wu 2019-04-30 06:38:52 UTC
Personally I think the pango package doesn't need to require ImageMagick or GraphicsMagick.
It seems only the ft2 backend will use display, and print warning if not installed.

IIRC, GraphicsMagick is better maintained for security issues.

from the upstream pango perspective: not a bug

This message is a reminder that Fedora 29 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 29 on 2019-11-26.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
Fedora 'version' of '29'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 29 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
