[FFmpeg/filters/overlay] PNG over a movie doesn't look write in 0.7

I'm trying to overlay a static PNG file over a movie with FFmpeg 0.7-rc1 but the PNG file is not rendered correctly.
The same command line produces the expected result with FFmpeg 0.6.9-rc0.
ffmpeg -v 9 -loglevel 99 -i chuck_intro_lq.webm -acodec copy -vf "movie=vert_100x100x32.png [wm];[in][wm] overlay=W-w-10:H-h-10 [out]" chuck_intro_lq_overlay_ffmpeg-0.7-rc1.webm
Please note that I've also tried with libxvid codec and an avi container; the result is the same (not correctly rendered picture).
The picture is a plain opaque green square saved in a 32bits PNG (with alpha channel).
It may be that I'm doing something wrong, but why was it working in 0.6.9-rc0.
