extfs uace broken with unace-nonfree 2.5-9 on xubuntu 17.10

[marcelpaulo]

When opening an ace archive, mc shows:

uace vfs not working: Inconsistent extfs archive

Latest unace-nonfree (2.5-9 on Xubuntu 17.10) is not showing full filenames, and there's no option to make it do it. Here's the output of unace l for the attached ace file:

Apologies, the ace archive was too large (85 MB) to attach directly, so I've uploaded it here: ​https://1drv.ms/u/s!AlsiEMDuBseItC-X2FDXqFBM2uNy

Forgot to add, I am using mc 4.8.19-1

Not sure how we can fix this if the unarchiver is not supplying the filenames and there is no option to make it do so?!
