help is opening in a TEXT EDITOR
How does gimp choose the app for viewing help? I do not have webkit, so I need an external browser. Even though I set the default app for text/html, text/xml, and application/xml to kfmclient (konqueror), gimp help always open in a TEXT EDITOR, which is the stupidest thing it could do.

I checked that
xdg-open /usr/share/gimp/2.0/help/en/index.html
does indeed open in konqueror, as desired.

The only thing that works so far is to uninstall the text editor, which again is the stupidest thing to do.
I have used various linux KDE distros since 2004 (Mepis - PClinuxOS - now Kubuntu 16.04) and for most of the time Gimp F1 help, either local or on-line has not worked.

Just tried all sorts settings, nothing seems to work for me. Different browser (firefox), changing system settings..etc.

Having said that just tried a xubuntu 16.04 VM with firefox as the webbrowser and that works fine. Must be a KDE thing.

For that reason I do not even bother having help installed and use a PDF version from
Searchable and with an index, a good off-line alternative.

Since you find xdg-open /usr/share/gimp/2.0/help/en/index.html works, an option is make that into a shortcut. You would have to start help separately but at least that would allow you to keep your text-editor Wink

Out of curiosity. Which KDE linux are you using?
I use Kubuntu 16.04 and the help works (remote version in Firefox). I assume Gimp uses whatever is defined to open HTML files in GTK.
Looking at my very basic Kubunto 16.04 virtual machine + stock Gimp 2.8.16 + help installed from the repo.

With local help enabled in Gimp I get a
"Calling error for procedure plug-in-web-browser No application is registered as handling this file"

If I enable on-line help I get a message ending
"Perhaps you are missing GIO backends and need to install GVFS?"

Installing gvfs and gvfs-backends (pulls in a raft of dependencies) does get the on-line help working. (I recall that this never worked in my PClinuxOS instalation)

Strangely also gets the local copy working as well. Maybe that will fix the OP's problem

Still prefer the PDF version.
Gvfs requires a lot of gnome stuff, including some daemons, so no thanks.

I am compiling webkit now, so that gimp can have its own help browser. I was hoping for a simpler solution. THis has been compiling for hours.

To answer the question, the DE is Trinity (KDE3).
oops, hit the post button too many times
