Wrong thumb_height in database for movies - streched thumbs

I have updated to Gallery 3.0.9 (Chartres) and I use and used recangle_thumbs (4:3).

Thumbs of new uploaded movies are now displayed streched. The image-dimensions are correct but the value of thumb_height in database is wrong (or may be better to say: seems to be set to the default value of thumb_size (150)).

For photos everything is fine. I get recangle thumbs with thumb_height 113 and thumb_width 150 in database.

I noticed that there have been changes in graphics::generate but have no clue where thumb_height for movies is saved to database.

Thanks for your help
