Images referenced by absolute path don't load

[Gunnar Hjalmarsson]

The latest yelp version in Xenial doesn't show SVG icons in Ubuntu Help. Example icon:

/usr/share/icons/ubuntu-mono-light/status/22/system-devices-panel.svg

SVG files are displayed in GNOME Help, but there they use relative paths to the files (included in package). Don't understand why that would make a difference, though.

Another issue is that calling yelp with the path to a .page file as argument fails with: "Unknown Error - URL cannot be shown".

Downgrading to the Wily version 3.16.1-1ubuntu1 of yelp and libyelp0 fixes both issues.

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

[Gunnar Hjalmarsson (gunnarhj)]

The issue with calling yelp with a file path as argument has been fixed upstream:

https://git.gnome.org/browse/yelp/commit/?id=e5f3a147aec6aeb4629194e1d3a3eefc1d4716e9

The attached patch cherry picks that fix.

I also committed a change to ubuntu-docs which replaces absolute paths to ubuntu-mono icons with relative paths to icons within the ubuntu-docs package. That's apparently not a real fix, but a workaround which may fix Ubuntu Help for 16.04.

@Doug: The latter includes changes of translatable strings, so we'll need to upload again very soon to update the translation template. Would appreciate if you could take a look first, though.

This bug was fixed in the package ubuntu-docs - 16.04.2

---------------
ubuntu-docs (16.04.2) xenial; urgency=medium

  * Use relative paths to SVG icons within this package instead of
    absolute paths to icons of the ubuntu-mono package (LP: #1559070).
  * Updated ubuntu-help.pot.

Well, it was not quite fixed in ubuntu-docs 16.04.2. Forgot to update ubuntu-help/Makefile.am, so the icons in question were not installed.

Committed the missing piece to bzr, and confirmed that it now works by uploading to this PPA:

Done yelp. Please upload the docs to workaround this.

Changed the title to reflect the upstream bug report, and re-opened the yelp (ubuntu) task. Even if we work around the problem with absolute paths to images in ubuntu-docs, other packages which rely on yelp might be affected of this issue.

A simpler workaround mentioned by Shaun McCance in the upstream bug report:
