Bug 1290077

*** Bug 1292310 has been marked as a duplicate of this bug. ***

It isn't elegant, sure, but `desktop-file-validate` doesn't complain, and it makes more sense to use that as a reference...  I've committed Peter's suggestion from #1292310 for `mkdir -p` in the exec entry, in any case.

I'll get some guidance from some KDE folks on this, I think.  It *is* marked as OnlyShowIn=Gnome, but it makes sense that KConfigIni would need to parse it to find that out.  The alternatives off the top of my head would be to ship a wrapper script to exec, which seems excessive for a oneliner, or to stop using epiphany, which would take away the 'integrated' appearance of the document in Gnome.

Independently from its elegance, the escaping sequence is indeed wrong and should read:

Exec=sh -c "PROFILEDIR=\"\$HOME/.config/epiphany/fedora-release-notes\";DOC=\"/usr/share/doc/fedora-release-notes/index.html\"; [ -d \$PROFILEDIR ] || mkdir \$PROFILEDIR;epiphany --application-mode --profile=\$PROFILEDIR \$DOC || xdg-open \$DOC "

(notice the two additional backslashes around the DOC= string)

But indeed the question remains: why not use only xdg-open which is "universal" instead of introducing complex "Gnomisms"?

And as an afterthought: why should release notes be shown only in Gnome? (KDE seems anyway to ignore the "OnlyShowIn=Gnome" sequence)

Eric's solution still causes the error.

Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

Reopening as I'm still seeing this behavior on my KDE F27 machine.

Also on Fedora 28.

Yes, still present in f28:

$ kbuildsycoca4
kbuildsycoca4 running...
"KConfigIni: In file /usr/share/applications/fedora-release-notes.webapp.desktop, line 7: " "Invalid escape sequence "\""."

"KConfigIni: In file /usr/share/applications/fedora-release-notes.webapp.desktop, line 7: " "Invalid escape sequence "\$"."

Still present in f29.  Maybe it will never be fixed :-)

Still there with KDE 5 in F30. Doubling all the backslashes makes the ksycoca5 warning going away, but I have no idea if it will still work on the GNOME side:

Exec=sh -c "PROFILEDIR=\\"\\$HOME/.config/epiphany/fedora-release-notes\\";DOC=\\"/usr/share/doc/fedora-release-notes/index.html\\"; [ -d \\$PROFILEDIR ] || mkdir \\$PROFILEDIR;epiphany --application-mode --profile=\\$PROFILEDIR \\$DOC || xdg-open \\$DOC "

Note that that amended line also includes Eric's additional backslashes around the "DOC=..." string.

This package has been retired.
