Sorry, can't relate times exactly. It was after I installed all the libav and gstreamer libraries, and it happens every time. Personally, I don't see a connection with the logs, but it seems to me that the issue has started after Nautilus was upgraded to 3.37.90. The older ones (e.g., 3.37.3 or 3.37.1) didn't have the issue.

Nautilus is no longer showing thumbnails (generated by Totem) for some video files, although the Totem thumbnail generator (totem-video-thumbnailer) is working. Nautilus is showing thumbnails for video files with (Ogg) Theora codec content (even if wrapped in a non-Ogg file format, such as mkv), but not for others, although I have installed all the required/usual libraries (libav*, gstreamer1*). Deleting the thumbnail fail cache (~/.cache/thumbnails/fail/) does not help. Installing ffmpegthumbnailer does not help either. This seems to be a regression, or maybe some libraries for video files in non-free codec formats have not been updated properly.
