I am able to reproduce this easily on krillin using image 16. However
thumbnails are generated correctly in the gallery on mako, so I don't
believe the issue is related to the gallery app itself but rather
something on the system. Also, I don't think it's a gstreamer related
issue, as the thumbail is correctly displayed in the video scope so if
it was a gstreamer issue it would fail there as well.
It could be a security/apparmor related issue. I see these DENIALS in
/var/log/syslog when launching the gallery when there are video
thumbnails:
