By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Description yehjj 2014-03-08 04:01:27 CST 
After upgrade to Fedora 20, run command "kttsmgr", a blnk icon shown in kicker. After google this issue, it seems original icons only compatiable with "libpng-1.2" not "libpng-1.6".

To workaround this, Install package "kde-dev-scripts" first, then execute the following command to : 
$ (cd /opt/trinity/share/icons/ ;/usr/bin/optimizegraphics)

After "optimizegraphics" convert all icons under directory "/opt/trinity/share/icons/", run command "kttsmgr", The icon shown in kicker again now. But it seems not fix all the issue due to not all icons are under directory "/opt/trinity/share/icons/".

Perhaps the better way to fix this issue is rebuild packages for Fedora 20 by Modify the "*.spec" file:
+BuildRequires: kde-dev-scripts
%install:
(...........)
+(cd %{buildroot} ;/usr/bin/optimizegraphics)

I do not known if the convertd icon should also compatiable with other distribution. If so, the best way to solve the issue is to run "optimizegraphics" under TDE's source code tree and commit it as a patch to fix it permanently.

I confirm the icon display issue.
I guess this will occur on any distribution using libpng >= 1.6

Maybe we should simply "repair" all the PNG image the git tree...

Perhaps add this bug report to the R14.0.1/R14.1.0 meta bug tracker?
Comment 5 Darrell 2015-01-25 22:12:53 CST 
Francois,

In bug 2295 you mentioned a conversion script. Do you have access to the script?
Comment 6 Michele Calgaro 2018-08-02 01:28:09 CDT 
Francois. does this bug applies to recent version of Fedora too? Is it still valid?
Comment 7 Francois Andriot 2018-08-02 12:32:16 CDT 
I believe all PNG images in TDE were fixed some time ago.
Also, today all Linux distribution use libpng >= 1.6, so if this bug still existed, it would affect everyone.
