** Description changed: - When using the ballery app, the thumbnailer gets loads of requests with + When using the gallery app, the thumbnailer gets loads of requests with QSize(-1,-1), for example, when opening the gallery app. The problem with this is that the thumbnailer interprets this to mean "give me the largest size you can (limited to a 1920x1920 bounding box). That's very expensive, especially in terms of disk space, because that 1920 "thumbnail" ends up going into the cache, needlessly hogging space. We are about to add a qWarning message to the QML side that reports invalid QSize requests. For now, we are going to retain the old behavior, but this will turn into an error soon. The most effective way to use the thumbnailer is to simply ask for an image in the desired size, with neither width nor height of -1. The thumbnailer will efficiently produce a thumbnail for that. (We do lots of internal caching to avoid extracting or downloading a thumbnail unnecessarily.) The thumbnailer may deliver a thumbnail that is smaller than what was asked for (because it never up-scales) so, if asked for a thumbnail of size 256, it's guaranteed not to be larger, but might be smaller (if the original image is smaller than what was asked for). Could you please adjust the gallery app behavior to ask for specific, valid sizes only? Running a tail -f on ~/.cache/upstart/dbus.log allows you to see the requests as they are made. Each request shows the size that was asked for.
