mpv not working in Debian Sid

Hi,

It seems that there is a problem with mpv and libass9 from DMO with
Debian Sid. When I start mpv, I get:

mpv: symbol lookup error: mpv: undefined symbol: ass_configure_prune

Googling, I found this:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1113926

It seems that removing all DMO files fixes the problem. Is there any
alternative?

Thanks!
