Activating Thunar Fails When Installing Xfce

[m5comp]

When I try to install xfce, the process comes to a stop when an attempt to activate the dependency Thunar is made:

:msg:activate --->  Activating Thunar @1.6.12_0

Does /usr/bin/tar exist? It should.

Are you using trace mode? If so, try not using trace mode.

Yes, /usr/bin/tar exists. I have tried using trace mode, and that did not help.
