Insync-thunar dependencies fail (arch)

When I try to build insync-thunar on Arch ( https://aur.archlinux.org/packages/insync-thunar/ ) I get the following error:

error: target not found: thunarx-python-0.3
==> ERROR: 'pacman' failed to install missing dependencies.

But when I try to manually install that, I get:
*** The required package thunarx-1 was not found on your system.
*** Please install thunarx-1 (atleast version 0.4.0) or adjust
*** the PKG_CONFIG_PATH environment variable if you
*** installed the package in a nonstandard prefix so that
*** pkg-config is able to find it.
==> ERROR: A failure occurred in build().
Aborting…

I noticed that there is a more recent version of thunarx-python, but I could not install it due the presence of a conflicting version:

==> Installing thunarx-python package group with pacman -U...

looking for conflicting packages...
error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: python2-thunarx and python-thunarx are in conflict
==> WARNING: Failed to install built package(s).

What packages do I actually need to make insync-thunar work on Arch?

Hi @prime_stranger,

The Arch builds have always been maintained by the awesome AUR guys, but let me check with our engineers to see what needs to be done to get insync-thunar running on your machine!

Hi @prime_stranger, can you try removing that dependency from the PKGBUILD before building and installing it?

https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=insync-thunar

Have try that, the thunar app crash totally. The problem is that thunarx-python-0.3 is not maintained anymore.
