I can't get dolphin to stop reloading and recreating the video thumbnails EVERY time i open the folder, instead of useng the cached thumbnails, i think this is happening after upgrading to 4.9.1

I'm using gentoo for amd64

This is normal or i'm doing something wrong?

I found it:

kffmpegthumbnailer-1.1.0-r1.ebuild

src_prepare() {
sed -e "s:CacheThumbnail:X-CacheThumbnail:" \
-e "s:IgnoreMaximumSize:X-IgnoreMaximumSize:" \
-e "s:ThumbnailerVersion:X-ThumbnailerVersion:" \
-e "/Encoding=UTF-8/d" \
-i kffmpegthumbnailer.desktop || die "fixing .desktop file failed"
kde4-base_src_prepare
}

I think that line is the culprit, i'll make a bug report in the gentoo bugzilla.
