bug#23452: Reconfigure worked after trying a second time

[Albin]

After trying to reconfigure a second time (from the same commit) the
problem didn't occur and the operation was successful.

I rebooted into the new system and the command 
`ls -la /gnu/store/72cp43sqala9j0hn3fsy5bcsc8whgjqb-clutter-1.24.2` 
now outputs:
