[SOLVED] Slackware-current info:/ protocol cannot be initiated in Konqueror

Maybe it is not much of importance but I liked ability of Konqueror to display manuals and info pages. Just in address bar input

# ls

this should show manual for 'ls' (but probably requires MANPATH to be set - by default is unset). I did this

## coreutils

which should show info pages for 'coreutils'. But instead I got this

The requested operation could not be completed Cannot Initiate the info Protocol Technical Reason: Unable to Launch Process Details of the Request: URL: info:/%20coreutils Protocol: info Date and Time: Monday, October 29, 2018 10:17 PM Additional Information: Description: The program on your computer which provides access to the info protocol could not be started. This is usually due to technical reasons. Possible Causes: The program which provides compatibility with this protocol may not have been updated with your last update of KDE. This can cause the program to be incompatible with the current version and thus not start. You may have encountered a bug in the program. Possible Solutions: Update your software to the latest version. Your distribution should provide tools to update your software. Contact your appropriate computer support system, whether the system administrator, or technical support group for further assistance.

it does not have much sense. When I was using KDE (actually 3.5) it was really useful.

You have to patch /usr/share/apps/kio_info/kde-info2html form kde/kde-runtime-4.14.3-x86_64-7.txz package.

In patch format, it is as following :

How did you find this? Does it official patch?

This is the last patch on this file in the kde-runtime's sources.

The upgrade to the recent version of kde-runtime solves the problem. You need this version

$ ls /var/log/packages/kde-runtime-4.14.3-x86_64-8

or any forthcoming (higher).
