Jehan 042d3051c6 app, libgimpbase: do not try to open a non existing file.
Now that GimpParamSpecFile makes file validation depending on the action
set in the param spec, when trying to open a non-existing file (which
can happen through GUI, for instance when opening through the Document
History dockable or Open Recent menu), we had a quite obscure error
about a value "out of range" used "for argument 'file' (#2, type
GFile)", which is because core tried to set the GFile for a non-existing
file into the second parameter of the plug-in PDB. This is not a very
nice error for end-users.

The old error was much nicer as it used to say things like:

> Could not open '/path/not/existing.png' for reading: No such file or directory

But in fact, this string came from the plug-in, which means:

* first that the error can be different depending on the format
  (inconsistency of error message);
* depending on bugs in plug-ins, it may just crash or return no error
  messages;
* finally we were making a useless call to a load plug-in while we
  should already know from core that it won't work.

The new message is something like:

> Error when getting information for file "/path/not/existing.png: No such file or directory

This error is generated by core, so it will always be consistently the
same, is understandable too and the plug-in won't even be called.

As a side related fix, I updated the GimpParamSpecFile validation to
only validate local files, just like we do in core. Remote files can
always be set (and we let plug-ins handle them), at least for the time
being.

                   ------------------------------
                   GNU Image Manipulation Program
                       3.0 Release Candidate
                   ------------------------------

This is a release candidate for upcoming version 3.0.0 of GIMP.
This is not considered stable yet, unless testing tell us it is.
Therefore save your work early and often. If you want a stable
version, please use GIMP 2.10 instead.

If you think you found a bug in this version, please report it! We are
at the verge of releasing the next major version of GIMP, so any report
helps.

If you want to hack on GIMP, please read the file devel-docs/README.md.
For detailed installation instructions, see the file INSTALL.


1. Web Resources
================

GIMP's home page is at:

	https://www.gimp.org/

Please be sure to visit this site for information, documentation,
tutorials, news, etc.  All things GIMP-ish are available from there.

The latest version of GIMP can be found at:

	https://www.gimp.org/downloads/

We also have a website dedicated to documentation at:

        https://docs.gimp.org/


2. Contributing
===============

GIMP source code can be found at:

	https://gitlab.gnome.org/GNOME/gimp/

Resources for contributors:

        https://developer.gimp.org/

In particular, you may want to look in the "Core Development" section. Some
articles of particular interest for newcomers could be:

* Setting up your developer environment: https://developer.gimp.org/core/setup/
* GIMP Coding Style: https://developer.gimp.org/core/coding_style/
* Submit your first patch: https://developer.gimp.org/core/submit-patch/


3. Discussion Channels
======================

We have several discussion channels dedicated to GIMP user and
development discussion. There is more info at:

        https://www.gimp.org/discuss.html

For the real junkies, there are IRC channels (e.g. #gimp or #gimp-user)
devoted to GIMP on GIMPNet (a private free software oriented network).
Many of the developers hang out there. Some of the GIMPNet servers are:

	irc.gimp.org:6667
	irc.us.gimp.org:6667
	irc.eu.gimp.org:6667

More discussion channels, such as forums, will be listed on the above
"discuss" page when they are moderated by a team member.
Links to archives of former discussion methods (e.g. mailing lists) are
also included in that page.

4. Customizing
==============

The look of GIMP's interface can be customized like any other GTK+ app
by editing files in `${XDG_CONFIG_HOME}/gtk-3.0/` (settings.ini and
gtk.css in particular) or by using "themes" (ready-made customizations).
Additionally, GIMP reads `${XDG_CONFIG_HOME}/GIMP/2.99/gimp.css` so you
can have settings that only apply to GIMP.

You can also manually change the keybindings to any of your choice by
editing: `${XDG_CONFIG_HOME}/GIMP/2.99/shortcutsrc`.
