Package: kdelibs
Version: 4:3.5.10.dfsg.1-2
Severity: normal
Tags: patch
Hi,
Now that debian has switched to KDE 4, the standard "Help -> Handbook" menu
entries fail for KDE 3 applications, typically with an error such as
"Could not find service 'khelpcenter'".
If you wish to explicitly reproduce this bug, you can install regina-normal,
run the program regina-kde, and try Help -> Regina Handbook. However, I
expect the same thing will happen for almost any KDE 3 app.
It seems that KDE 4's help centre is indeed able to read KDE 3's docbook
help files; it's just a matter of pointing KDE 3 applications to the
correct help viewer. The ubuntu people fixed this in jaunty by patching
KApplication::invokeHelp() -- the relevant patch is
kubuntu_98_fix_khc_invocation.diff, and I have included it below.
I would be grateful if debian could apply this to its kdelibs packages
also -- this would be a great help for the usability of KDE 3 apps,
by restoring easy access to documentation.
Thanks - Ben.
