konqueror info protocol no longer works

[adam plaice]

Running:
16.04.1 LTS

kde-runtime:
  Installed: 4:15.12.3-0ubuntu1

To reproduce:

Enter info:/coreutils/Top into the konqueror URL bar.

Expected result:

Konqueror displays relevant info page.

Actual result:

The following error message is displayed:

"
The requested operation could not be completed

Cannot Initiate the info Protocol

Technical Reason: Unable to Launch Process
..." (attached in full)

This appears to be the same bug as reported upstream here: https://bugs.kde.org/359015

Applying the patch in the above report to /usr/share/kde4/apps/kio_info/kde-info2html seems to fix the problem:

Note: I've reported this to kde-runtime, because:
dpkg -S /usr/share/kde4/apps/kio_info/kde-info2html
states that kde-runtime is "responsible" for this file.

If I've reported it in the wrong place, I apologise.

Status changed to 'Confirmed' because the bug affects multiple users.

Still seen in ubuntu artful even with the kde backports.

There is no visibile error message with konqueror, but the browser seems to remain stuck in trying to load a page when entering

info:dir

Same goes with falkon (yet I do not know if the kioslaves are expected to work there).

Please consider removing the info ioslave if unmaintained.
