Awesome, thanks for looking into this.

Applied!

‘guix lint’ reports this:

  gnu/packages/image-processing.scm:201:2: opencv@3.4.1: probably vulnerable to CVE-2018-7712, CVE-2018-7713, CVE-2018-7714

Could you take a look?  It could be that 3.4.2 is around the corner and
we’ll just update at that point; if not, we may have to apply upstream
patches for these issues.

Thank you!

Ludo’.
