Description of problem: png images cannot be displayed anymore using perl-Tk's Tk::PNG module. This is probably related to https://rt.cpan.org/Public/Bug/Display.html?id=87016 The problem does not appear anymore with a development release of Perl/Tk, e.g. SREZIC/Tk-804.031_502.tar.gz Version-Release number of selected component (if applicable): perl-Tk-804.031-4.fc20.i686 How reproducible: Steps to Reproduce: 1. Try the following oneliner with a random png image: perl -MTk -MTk::PNG -e '$mw=tkinit;$mw->Label(-image => $mw->Photo(-file => shift))->pack; MainLoop' pngtest.png 2. 3. Actual results: Error message "invalid after png_start_read_image or png_read_update_info at /usr/lib/perl5/vendor_perl/Tk/Image.pm line 21.", no png image is displayed Expected results: png image should be visible in a X11 window, like it's the case with fedora 19. Additional info:
Confirm this is still an issue in Fedora 21 and causes, for example, Mapivi to fail on start: > ./mapivi Mapivi 0.9.7 - Martin's Picture Viewer and Organizer Copyright (C) 2002 - 2008 Martin Herrmann Mapivi comes with ABSOLUTELY NO WARRANTY. This is free software, and you are welcome to redistribute it under certain conditions. invalid after png_start_read_image or png_read_update_info at /usr/lib64/perl5/vendor_perl/Tk/Image.pm line 21. I assume any other Perl::Tk script would be affected similarly. Patch fix can be found via link posted in description.
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '20'. 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 20 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.
