SMime type unknown

[guiyou65]

I have different types of video in the gallery with various extensions such as .mp4 .m4v .webm. For all of them I get the message "smime type unknown". Very strange because it worked in a previous version. The webserver also hosts an owncloud instance where videos are playable with html5. So it should not be the server configuration.

I also get these warning during sync
