Update the thumbview visible range in an idle callback
This avoids entering in an infinite loop of unsetting a thumbnail, relayouting the iconview, updating the adjustment, setting the thumbnail, relayouting the iconview, updating the adjustment, unsetting the thumbnail, and so on. Bug https://bugzilla.gnome.org/show_bug.cgi?id=639312 Based on eog commit a395e95c5df2c4cbae9ce749544ec62820746e40 From Claudio Saavedra <[email protected]>
