Bug#844376: caja-actions: Uses deprecated libunique3

[Jeremy Bicha]

I didn't see your response until today since I wasn't explicitly CC'd
on your reply.

Why did you change the severity of this bug without an explanation?

libunique3 is unsuitable for release in buster according to its
maintainers but it cannot be removed from testing as long as
caja-actions is in testing with this bug unfixed.

Please investigate whether filemanager-actions can replace caja-actions.

Thanks,
Jeremy Bicha
