RawTherapee git: conflict file on Arch system

[maderios]

Conditions:
Arch system
Compiled sources
hicolor-icon-theme 0.17-3 package https://archlinux.org/packages/extra/any/hicolor-icon-theme/
Due to conflict file with hicolor-icon-theme, can't install/upgrade RawTherapee git since recent commit
May be this commit ? 7f45af1
When I try to install:

error: failed to commit transaction (conflicting files)
rawtherapee-git: /usr/share/icons/hicolor/index.theme exists in filesystem (owned by hicolor-icon-theme)
Errors occurred, no packages were upgraded.

@Pandagrapher Is the hicolor index.theme required for all Linux builds or just our AppImage?

[Pandagrapher]

@Lawrence37 If I remember well: rawtherapee icon shall be located in a hicolor icon theme folder to be set as AppImage icon. For other linux build, rawtherapee shall be located in an icon theme (not necessary hicolor one) to be used by the Gtk::Window::set_icon function. That's why I have answered to both needs putting the icon in an hicolor theme installed during linux/AppImage builds.

I don't know yet how to fix that issue the best.
